c/w: 🎀OOC🎀, fluff, gn!reader (I think), use of "my lady" in Suo's, established!relationship in Umemiya's

GRADUATING 2DAY RAAAHHH🗣️🗣️🔥🔥🔥🦅🦅🦅

—Haruka Sakura being the easily flustered tsundere he is, words and physical touch aren't really in his dictionary of how to express his feelings. He isn't good at being forward verbally in the environment of love, nor is he able to initiate close proximity gestures.

Without realizing, one of his particular ways of showing his care was through acts of service. Helping each other around town has become a normalcy. Thus, he wouldn't stand out when doing you a favor purely out of his own will; he prefers to be discreet to avoid getting called out, not wanting to be viewed as soft and lose his dignity.

He'd claim that he couldn't give any less of concern for anyone. Yet, he couldn't help but feel an uncomfortable tug at his heart when you mentioned forgetting to bring an umbrella during the rainy weather. He contemplated whether to do something about it or not, torn between his pride and feelings.

Just as you were about to step foot outside, you felt a hand on your shoulder that brought you to a halt.

“The hell do you think you're doin’? Trying to get a cold?”

You weren't given enough time to let out a reply before a folded umbrella was held up to your face.

“You could've asked to borrow one, y'know. I have a spare, so save the fuss and just take it.”

With that, you thanked him and gave a smile of gratitude before taking your leave with the lent umbrella. Little did you know, that boy did not own a spare…

—Hajime Umemiya is so pure he's guaranteed to shower you with every. possible. way. imaginable to express his love. But physical touch would be one of the most prominent.

No matter the occasion, no matter the time, you somehow will always get pulled into an embrace one way or another. He loved the feeling of cradling your petite figure between his strong arms; it made him feel like he was shielding you from any harm. His hugs were warm, comforting, and provided a sense of safety. He'd wrap his arms around your waist from behind and spoon you in, he'd rub his hand up and down your back as you cry into his chest, he'll run up to you and let you jump into his arms, spinning you around as he lifted you off the ground.

He loves the feeling of your hands against his; your soft skin contrasting with his calloused palms. The comparison between the size of your hands and his was somewhat cute to him, making him want to protect you even more as if you were the most precious yet fragile treasure in this world.

“Next time you come in here looking all beat-up, I'm kicking you out and locking you outside,” you scolded him as you tended to his injured hands, irritation yet concern etched on your facial features.

Ume let out a chuckle at your threat, gazing at your grumpy yet worried facial expression which he thought endearing.

“Aww… You really have the heart to be so cruel to your beloved and caring boyfriend??” he whined as he looked at you with an exaggerated pouty face.

“So-called ‘caring’ but doesn't even seem to care about how worried his girlfriend gets when he comes over looking like a used dog toy.” He felt a twinge of guilt at your words, feeling bad for making you so worked up over his condition.

Gently, he held your wrist and brought your hand up to his face, softly placing tender kisses on your knuckles.

“I'm sorry for worrying you, sweetheart…” His deep, gentle voice conveyed such words so smoothly, like a soothing melody strumming its way through your ears and into your heart. You couldn't help but loosen the wrinkles that tugged your eyebrows, letting out a sigh as the tension slowly left your nody. You knew it was his duty to protect the town and all, but the amount of fight he gets into this week devastated you.

“Just… try to avoid doing it alone, please? I know you're strong, but it hurts me seeing you go up against many by yourself.”

“I'll try… Promise.” With that, he leaned over to plant a reassuring kiss on your forehead.

—Hayato Suo enjoys being discreet and mysterious. He finds amusement in seeing your confused face when you receive any form of gift anonymously. At first, he'll start out completely unknown; he wants to satisfy his curiosity on how you'd react for the first time. Once he saw the confused yet happy look on your face, it made him want to perform the act of gift giving even further.

The type of gift would often be small flower bouquets. Occasionally, a little pack of candy would be stuck to it alongside a little note. Written inside those little notes; through either riddles, poems, or song lyrics, he started giving subtle hints on who the sender was. Day by day, he watched patiently as you took your time to connect the pieces.

Until one day.

You were at Pothos, helping out Kotoha as the first-year gang hung out. While wiping the front counter, you overheard Nirei sharing his opinion on how cool Suo was that he understood flower language. You internally agreed. Suo was a man of many quirks, and you've secretly admired him for that. He understood trivial things that most people wouldn't; poems, flowers, riddles– Holy shit.

Your body froze up the moment realization kicked in, heartbeat accelerating as you tried to quickly form everything in your mind. The elegant handwriting, the heart touching poems, the beautifully arranged varieties of flowers. Could it be–

“Suo.”

The crowd suddenly went quiet at the abrupt mention of one of the personel. You decided to take things somewhere a little more private.

“Please be honest with me,” you demanded as the both of you stood in front of the café.

“Are you the one who has been placing random flower bouquets in front of my doorstep? And before you come at me, there is no one else I know that understands flower language, poems, or-”

“Ah, so you've finally noticed,” the brunette chimed innocently with a sweet smile.

You blinked. “W-What?”

“Yes, I'm the perpetrator behind all those floral gifts you find every day. Are you uncomfortable with it? I can stop if you'd like–”

“NO! I-... I appreciate it. It's just… why? What for? Did you get a dare or something?”

Ever so subtly, his eyes softened at your words. “Why, it is simply because I like you.”

The moment the confession escaped his lips, it felt like your whole world was shaken. You were excited, happy, yet unsure. Unsure if he meant it or not. After all, you knew the kind of person he was.

“... Please don't joke about this.”

He understands what you mean, and he doesn't blame you for that. “My lady… I may be one to bluff, but involving one's feelings is where I draw the line,” he spoke with a tone oh-so gentle, wanting to convey the sincerity his words bore.

“Then… what are you trying to get out of doing all of this?”

“Your heart.”

Blood rushed into your cheeks like a marathon. Your heartbeat acceleration exceeded a speed limit you didn't know you had. With a deep breath, you gathered all ability left to respond.

“... You already did.”

Not even a second passed, and the young man felt a pair of arms embracing him tightly; a sigh leaving his lips as he looked down at the fair maiden in adoration and fondness.

Little did they know about the little audience they had through the glass window of the café.

—Ren Kaji has an aloof demeanor that he tends to keep to himself and distance his existence from the world. He's not one to listen nor speak, preferring to focus on the music blasting through his headphones. Though he enjoys being in rowdy places, he doesn't get loud and excited himself. All in all, quality time would be his best aspect in the language of love.

He'll accompany you on your walks, either when he bumps into you during patrol or when you're going home from school. He'd claim that walking you home was a part of his ‘duty’ and that you just happened to appear as an excuse. Along the journey, he'd listen to you talk your heart out while humming occasionally to let you know he was listening. Even if his headphones were on, he'd lower the volume to be able to hear your voice.

Never had he admitted how he felt comfortable with your presence, and maybe he never will. Words and touches weren't in his field of knowledge, making him seem to be difficult to approach. But little did you know that deep down, he held a spot for you as one of the exceptions – which he was clearly oblivious to.

“... Kaji… Kaji.” He rolled the sucker in his mouth and pulled down his headphones as he felt a poke on his cheek.

“Go on ahead without me. I'm gonna head someplace to eat.”

“I'll come with.”

“But you have patrol.”

“And I also have Enomoto and Kusumi. End of discussion.”

With a defeated sigh, you decided to eat at Pothos; the safest place to eat and thankfully the closest to your place. You offered to treat Kaji for dinner – not wanting to be the only one eating – but the young man declined and said he wasn't hungry. You didn't care; still getting him something as a way to thank him for his willingness to accompany this whole time.

“What? I said I wasn't hungry,” he claimed in defense while pulling his head away once he saw you bring a spoonful of omelette rice to his mouth.

“Just shut up and eat. I'm not living with the guilt for having you go through all this trouble for me.” You pulled out his sucker and replaced it with the awaiting spoon, not giving him time to argue back. He swallowed and looked away before muttering lowly.

“I'm not doing it for you.”

“Whatever you say…”

He begrudgingly let you feed him the whole food, chewing quietly and kept himself distracted on his phone. Unbeknownst to you and him, tints of pink adorned his cheeks.

Little did y'all know, Tamon's second year's vice captains had a good view, bur decided to save themselves a scolding.

These days I have been working on other drawings and finishing the ones I had pending, this is one of them, which joins the collection I already have 🤣

⸻ ღ ❝ WHAT IF I... ❞

you pop the question, asking him, “what if i disappeared one day?" his reaction?

ft. hayato suo, yamato endo, choji tomiyama, umemiya hajime, ren kaji, haruka sakura, kyotaro sugishita, jo togame x gn. reader (separate)

ღ HAYATO SUO ─ ❀ °. ⁺ ♡

He tilts his head to the side. "Whatever do you mean by that?" A brief flash of confusion crossed SUO's face before the ever-present smile of his returned.

"I mean, like, what if I just, from out of nowhere, went poof one day? What would you do?" you clarified with a smile. 

You couldn't quite figure out what was going through his mind as he let out a pensive hum, his index finger rhythmically tapping against his cheek, appearing to be in a deep moment of thought. Granted, you never did know what Suo is thinking about, something appeared to be different this time.

Suo knew that the question you asked was a mere hypothetical, similar to the ones where you'd find on random scenarios online—meant to be a casual inquiry intended to gauge his reaction, so he didn't give it much concern.

"Well then, if that's the case, as your boyfriend." He leaned down to whisper in your ear, "It's only right for me to find you and make sure you’re safe, isn't it?" 

He says it so matter-of-factly with a hefty amount of confidence that undoubtedly makes your heart flutter. There's no hesitation, no doubt in his voice, as if it's the most natural thing in the world. But the outside is indeed never what it appears to be, but also what can be the most deceiving. Suo doesn't worry too much about your question upfront, but there would be times when his mind would wander, drifting back to that single conversation that haunted his thoughts. What implored you to ever ask him that? 

And so, over the next few weeks, Suo would watch you with even more attentiveness than he already did, which was already considerable. Being by your side meant everything to him, and he couldn't imagine life without you if that were to ever ring true. After a few days of thinking, Suo's answer has not changed and will never change, but the realm of possibility that you might disappear will forever linger in his mind.

ღ YAMATO ENDO ─ ❀ °. ⁺ ♡

ENDO, with his piercing, sweatdropping gaze, doesn't even take a minute to look at you, and, instead, at himself. Not in the literal sense, but inwardly. He scrutinizes his every action, every word, trying to decipher what could have prompted such a question from you.

"Disappear?" he asks with a tone of sharp curiosity as he finally meets your nervous gaze. "Is that what you really want?"

Cupping his chin, all with the expression that he's about to beat someone half to death, Endo takes a quiet moment to himself and thinks about your question more thoroughly, which only makes you more anxious, in all honesty. 

With a sheepish laugh, you attempted to steer the conversation to a different subject, but Endo was having none of it. His intense focus was right then and there for you to answer.

Endo sits back down, covering his face with his calloused hand, letting out a low chuckle, "You must be either naive or plain stupid if you ever think that's going to happen on my watch.”

"H-Huh?"

"Because you're never leaving me." Endo’s voice carries utter conviction, a lifelong promise wrapped in a singular statement.

Endo snickers a bit from your seemingly adorable reaction before fading into an expression of distaste. His eyes bore into yours, filled with an emotion you can't quite place. "I don't know what brought this on, but let me make one thing clear. You're not going anywhere. Not without me."

He reaches out, his hand finding yours, gripping it firmly. You can feel the roughness of his skin, the callousness from all his previous fights, the strength in his hold, and it grounds you. A chuckle escapes him as he leans back, the seriousness melting away as a mischievous grin spreads across his face from ear to ear. "Besides, who else is going to put up with your atrocious cooking?"

ღ CHOJI TOMIYAMA ─ ❀ °. ⁺ ♡

CHOJI takes a moment to think. "Hmmm, well then. I'll just find you again! Simple and easy! Don’t you think?!”

You laugh alongside him, not having the heart to continue the conversation. But unbeknownst to you, Choji's light-hearted response hides a deeper concern. Choji may act childish, but he's not stupid. He knows that he's not perfect, and in fact, he's a very flawed human being who has done far more harm than he'd ever like to admit, and certainly not to his lover…

Thus, throughout the day, you would be subjected to Choji clinging onto you. Whether you like it or not, he becomes your shadow, sticking to you like glue. As for bathroom breaks? Well, sucks to be you, that's not going to happen without him hovering nearby like a mosquito.

You knew what this meant. Choji's playful manner masks the underlying fear of losing you, and he doesn't let you out of his sight. Whether it's following you to the kitchen or tagging along to every errand, Choji's constant presence lingering over your every move is both endearing and slightly overwhelming. He jokes and laughs, trying to keep the mood light, but you can see the worry in his eyes whenever he thinks you're not looking. It's clear that the thought of being without you is something he can't bear. Just thinking about how his life would be if you left was enough of a nightmare that he decides that possibility would never be considered.

Choji's answer remains constant, but don't let that distract you, his words are only the half of it. He'll never let you go, not on his watch.

ღ HAJIME UMEMIYA ─ ❀ °. ⁺ ♡

UMEMIYA is immediately alarmed by your question, pausing right in the midst of caring for his plants to turn to you with a rather distressed frown that deepened with every second. He jumps to grab your arm, perhaps in fear of you leaving right then and there, and asks with a nervous laugh, "Ahah… you're joking, right?” Was this supposed to be some kind of dare from Hiragi or Tsubaki?

And his grip will not loosen until you tell him the details, tenfold. Unlike the usual energetic demeanour he broadcasts to the world, Umemiya doesn't even try to hide the fact that he's worried, scared, with all but the absolute worst scenarios surfacing in his mind. Were you being threatened in some way because of him?

On the surface, he knows that you asked that question in a hypothetical sense, but that doesn't lessen his fear that it could happen, and your bringing it up helped trigger it. His past memories come right back to haunt him again.

And without thinking, Umemiya embraces you in a bone-crushing hug. "I-I don't know what prompted you to say that. Please… Hit me, get mad at me, yell at me, but please, don't ever leave me."

His grip tightens around you, desperation evident in the way he clings to you as if you might vanish at any moment. You can feel the tremor in his hands, the rapid beat of his heart against your ear. It breaks your heart to see him like this, so vulnerable and afraid. You gently stroked his back, whispering soothing words to calm his frayed nerves. Slowly, his breathing steadies, and he relaxes a bit in your arms, but the fear in his eyes still remains. It's clear that the thought of losing you terrifies him more than anything else.

His mind races, no, refuses to accept the thought of you ever disappearing from him. His answer was clear. He was never going to let that happen, not without a reason for closure. And so, Umemiya's efforts to spend more time with you would only be further amplified from there. 

Waking up in the morning? Umemiya would be out your door soon enough with a bed-in-breakfast. Getting groceries? Umemiya will once again be there to be your personal bag-handler and bodyguard. You'd have to reassure him plenty in order to convince him that nobody is out to get you and that you aren’t in danger by any means. But even then, that was not going to work either, oh no. 

As the leader of Furin, Umemiya would make sure that you were protected at all times, sending only the best and closest friends to watch over you and make sure that you were safe. Sakura would snort and mutter under his breath that "that guy is overdoing it," only to receive a stern look from Nirei and a withering glare from Hiragi and especially, if in the presence of the man himself, Umemiya.

How on earth could you tell him by that point that it was all a joke…?

ღ REN KAJI ─ ❀ °. ⁺ ♡

Admittedly, KAJI does not think much of it as he continues to listen to his music with your head resting comfortably on his lap. What do you mean you're just going to leave? Without him? Impossible. 

He hums before going back to indulging his lollipop, which, by all means, was his solace. But later on, Kaji's mind drifts back to the question you asked. His eyebrows fold into two thinly knitted lines as he processes what could ever be your reasoning for asking such a thing. Not even the most relaxing of music could calm his mind as he begins to overthink every little detail of your relationship, replaying every conversation, every moment you've shared, searching for clues or hints he might have missed that made you want to think that.

The thought of you leaving gnaws at him—a rather unsettling and even unfamiliar feeling that he can't shake off no matter how hard he tries. Kaji debates with himself whether to bring it up with you again or let it slide, not wanting to seem insecure but also desperate for reassurance and that what he heard wasn't actually true.

His heart races with each passing thought, and he finds himself pacing back and forth while outside your homeschool, trying to make sense of his swirling emotions. That is, until you ask him with a confused frown what he was doing.

He doesn't wait for a response but instead pulls you straight into his arms. Kaji grabs both your shoulders and apologizes. He stares right into your wide eyes, and he finally confesses, "If you disappeared… then I wouldn't know what to do with myself."

Kaji gulps in the air like someone who's drowned. He hardly even knew what to do with himself, just pondering the answer about a mere possibility. If that ever came to fruition, he'd be utterly lost. Though he guards his heart carefully, he's unrestrained with his body, whether for comfort or for pleasure.

He holds you firmly. Implacably. He will hold you all night if needs must, and throughout the day. His grip shifts to a tight hug as if trying to squeeze out all the sadness with his strong arms. "So please, don't."

With a heartfelt sigh, the tightness in your shoulders relaxed and you caressed his back with a gentle hand, all while comforting with your voice—the same voice Kaji grew to love with all his heart.

ღ HARUKA SAKURA ─ ❀ °. ⁺ ♡

Rolls his eyes. "What do you mean you're just going to disappear?" SAKURA clicks his tongue. "As if that's ever going to happen."

But in reality, despite his outward words, Sakura is far more concerned than he initially lets on. His composure can only stretch so far until he loses it. Quite literally. He may put on a brave face, but the thought of you vanishing haunts him. He starts by subtly interrogating your friends, your family, and anyone who might know something. His questions are cloaked in casual conversation—well, as casual as Sakura thinks—but the urgency in his eyes betrays his true feelings.

He becomes much more protective from then on, always by your side, watching you with a worried gaze that he often tries to mask. But you, in fact, do notice the change, the way Sakura hovers a little closer to you when he's, without exception, extremely volatile to physical touch, his touches lingering a little longer, and his blatant need for confirmation that you're not going to leave. 

Until, one day, out of nowhere, Sakura answered the question. "If you leave… then I won't stop until I find you. That's it," he muttered in a voice so low that you could hardly believe it, your eyes widening in surprise.

"Haru, could you say that again?" you asked, voice trembling with emotion.

“Huh?”

“Just now, could you repeat it?”

Sakura grumbled, scrunching his flushed crimson face into a grimace. "Y-You idiot!! I already said it!!!"

"But I want to hear it again…" you pouted, feigning sadness, making Sakura blush even further, his ears a deep crimson.

"Tch… I'm just telling you, if you disappear one day, I'm just going to find you, and I'll keep trying until I do."

ღ KYOTARO SUGISHITA ─ ❀ °. ⁺ ♡

SUGISHITA is eerily silent. Usually, that wouldn't be as much cause for concern, but there was something different in Sugishita's expression that unnerved you. Disappearing? That was a joke, right? No… you probably meant something else. You did mention that you planned to go out to buy groceries later that week. Could it be because of that? Or perhaps…

Sugishita, in his inward panic, grabs your arm with a grip tight enough to completely cut off the blood circulation to the rest of your body. "You're… going to leave? How? …When? W-Why?"

You could see that Sugishita was becoming increasingly anxious, his mind seeming to be practically in another dimension. With a pat on his head, you reassure him that you meant it all as a hypothetical question and that you aren't going to leave by any means. But the damage had been done. Sugishita, being the worrywart, needed far more confirmation than just that.

And just like Choji, for the next few days, Sugishita would be watching your moves like a hawk, standing at your side, towering over you. His eyes follow your every move. His piercing eyes staring into your soul felt almost suffocating, but it was clear that he couldn't bear the thought of losing you, even for a single moment.

Umemiya, with his usual bravado, burst out into laughter as he claps Sugishita's flushed cheeks repeatedly, reassuring him once more that it was nothing but a mere misunderstanding and a curiosity for his answer on his part. Hiragi agreed, nodding his head along.

Nonsense, Sugishita thinks with a wry face. He will be the one to ensure your safety, replaced by a type of intensity that makes you feel, while protected, also slightly on edge with the burning stare that he insists on maintaining to keep watch, even when you shoo him away.

You knew that his actions came from a place of love from when you initially asked him that question, but even so, did you really need him to stand outside your classroom door…?

ღ JO TOGAME ─ ❀ °. ⁺ ♡

Your words would kick his mind into gear almost instantaneously. TOGAME's thoughts raced, his aloof demeanour spinning around in circles like a pertueral carousel as he considered the possibility. Togame eventually came to the harrowing conclusion that he wasn't enough for you, that you felt neglected, or worse, unhappy being with him. 

He stared at you, his eyes wide. "What do you mean by 'disappear'?" he asked, his voice trembling a bit despite his efforts to keep it steady.

Just the mere thought of that made his stomach churn and his chest tighten. He couldn't bear the idea of losing you, even if through the lens of a mere hypothetical question. Togame, usually so stoic and composed, felt his facade crumble before your very eyes. Regardless, he was still intent on proving his worth and winning you back, all in the name of rectifying whatever he had failed to do.

You could see the pure, unfiltered, raw emotion in his eyes, the sheer terror of losing you. "Oh no, Jo, I didn't mean it seriously! I was just curious," you said In hopes of smoothing him, but the worry etched on his face didn't fade.

"...it's not something I can just ignore," he said, voice growing firmer. "If you ever feel that way, if you ever think about leaving, please, talk to me first and we can communicate… Let me fix whatever is wrong.l, whatever it is. Because the thought of you not being in my life is unbearable…" He reached out, taking your hands in his shaky ones. “You want to know my answer? I would search for you everywhere, and do anything to bring you back. You mean far too much to me to just let you go…”

His vulnerability was laid bare, even to your own surprise, who didn't expect this from a mere question. Togame would do anything to prove his love to you, to ensure that you never felt the need to ask such a question again. And in that, he certainly succeeded, because you would never doubt his devotion to you again, not that you did to begin with, but knew that it was a slippery slope and a topic to avoid when with him.

But, for good measure, after that conversation fiasco, Togame had taken up a new hobby. And you were more than happy until you realized what that "hobby" of his entailed, as friends or practically anybody who was an unfortunate passerby, would immediately notice a bodyguard-like figure constantly by your side. That is, until they saw the brute clinging onto you like a man desperate for even a whiff of your attention.

accurate representation of me after watching episode 11 and seeing kaji ren for only like...a couple of minutes...

next week I'm gonna go full unhinged mode I guess

imagine napping with ume thoughhh 😮‍💨 you know for a fact he’d cuddle. the man cannot and WOULD NOT fall asleep without having your limbs touching, feeling your warmth against his skin. can’t convince me otherwise.

if he could, he’d have his entire face shoved in the space below your neck, nose and mouth included. but he has to breathe, y’know? so he likes sleeping on your pillow. you gotta share.

when he wakes up before you, he peppers super gentle kisses along your face. sorry, pal. he absolutely cannot help it. if he had a tail, he’d be wagging it as soon as he saw your adorable sleeping face. (kisses would substitute the imaginary tail)

when you wake up before him, good luck. the man sleeps like a rock. at least you could stare at his pretty sleeping face for a few minutes, I guess? or you could pepper soft kisses on his face too if you wanna try waking him up.

a billion soft kisses to wake ume up just so you could see him wake up with a huge smile on his face? WORTH IT.
