On January 30th, 2023, you received a knock on your door that would alter your life forever.
You met your husband when you were ten years old. He was sweet and gentle, and you knew you would get married when you two got older. When you turned 18, he joined the military as a combat medic. He would always tell you he wanted to be a real-life superhero. At 22, he asked you to marry him. It was a beautiful beachside wedding. At 23, you gave birth to your son; you never saw yourself as a mother, and sure, Azra was a handful, but you were happy. By 25, you were a widow, watching as they lowered your husband into the ground, holding your crying son.
The date was February 14th, the day he was supposed to come home, but you didn’t think it would be in a casket. You weren’t allowed to see your husband one last time. You were told they had gone out on a medevac mission when their helicopter was shot down. In nicer words, they told you your husband was decapitated, and they never found his head. And that was the image you would have to live with forever. The image of your decapitated husband never coming home.
On the day of the funeral, his family showed you and your son so much compassion. His older twin brother, Taehyung, held your hand as he was lowered into the earth. Everyone expected you to be a mess, but no one knew that you and your husband prepared for this. He talked about it often to desensitize you. While his dying in combat was always a possibility, you never thought in a million years that what you two spoke about in private would become a reality. So while internally you were destroyed, on the outside, you were stoic, unphased even.
After the repass, you watch quietly as everyone leaves. The only person who stayed was Taehyung. He told you he stayed to help you and that it was customary for someone from the family to stay with the widow while she grieves. Since he had no female siblings, his mother asked Taehyung to stay.
“Hey, why don’t you go lay down?” he asks, taking a sleeping Azra from you. You just look at him, the dark circles under your eyes prominent. “Okay, I’m going to put him in the nursery, and I’ll be right back.”
It was silent when he walked away. Quiet enough for you to finally hear your thoughts. The inner turmoil is finally getting to you, and at this point, you are far too tired to hold it in anymore. So you let it out, sobbing loudly into the chaise. When Taehyung hears you, he bolts, the need to comfort you overwhelming him.
“Hey, hey, it’s okay. Everything is going to be okay,” he says softly, cradling you in his arms. You pound your fists into his chest, angry at the world for taking your person. Eventually, you lose the energy to continue, balling your fists into his shirt. After what seemed like forever, you passed out in Taehyung’s arms.
Taehyung sighs in relief. What did he know about comforting anyone, let alone his younger brother's widow? What was he supposed to do to help you? Nothing he could say would ever bring him back, and telling you everything would be okay would only comfort you for so long. And who would comfort him? He lost his best friend since birth. He wasn’t like you, though. He never kept it bottled up. When you called to let him know, he dropped to his knees, sobbing loudly into the receiver before hanging up. He cried every day leading up to the funeral and even at the funeral, but no one told him that they were sorry for his loss. They only focused on you and his mother, but what about him? What about how he felt? He lost his identical twin brother, someone he spent every day with for 18 years. He had always held a little resentment for you for stealing his best friend, but right now, he loathes you. You weren't the only one hurting. He didn’t even want to stay here with you while you grieve. He begged his mom not to make him but was met with a slap to the face.
Nonetheless, he picks you up gently and carries you to your room. He sets you down just as gently as if you would break if he weren’t careful. He grabs the blanket at the bottom of your bed and covers you with it, tucking you in. He stands over you, admiring you briefly. He hated you for many things, and one of them was for being so pretty. He pushes the thought away, too inappropriate considering what is going on, before turning to leave.
“Sujin?” you call out to him. Your dreams came true. He came back to you, “Come back to bed, don’t leave me again.”
“I’m not Su-” he can't finish the sentence. You won’t let him. You desperately want it to be your husband. You know deep down it isn’t him, but lying to yourself will help with the giant hole you have in your chest right now.
“Please, Sujin… I’m scared.” it comes out so weak and pathetic that it genuinely pains Taehyung to hear. His heart breaks for you, the hatred he had for you dissipating. But he still doesn’t turn to face you, so you plead for him again.
“Close your eyes…” he says softly. Taehyung decides to do this for you just once. He knew that it would hurt you more if he just walked away. It would hurt him just as much to pretend to be his brother, but he just wanted you to sleep. “Tell me when they’re closed.”
You tell him, and he walks slowly to the bed. He cups your cheek and runs his thumb against it softly. “I’m sorry, I didn’t mean to scare you…” You lean into his touch, and he joins you on the bed. “Let’s go to sleep.”
Taehyung takes you in his arms once more on this terrible day. You bury your head into his chest, and he strokes your hair. He swears he felt you kiss his collarbone, but he chalks it up to you being delirious. He wants to hate you so bad, but to hate you would be to hate a piece of his brother. He wants to get up and leave you to wallow in your sadness, but he knows that isn’t what Sujin would want. Taehyung hasn’t felt so conflicted in his life, but what he is sure of is that seeing you call out for your husband hurt him more than he expected. And what he was absolutely sure of was that he would never let you cry like that again.

When you woke up, you felt arms wrapped around you. So you turned slowly to see who it was, and the face you saw excited you, so you cupped his cheek softly. You moved to peck him gently and realized who it was before you did. You knew it wasn’t Sujin because of the small moles under his eye and on his nose. So you jolt up, startling Taehyung in the process.
“What hell are you doing in my bed?!” you move away from him quickly. Taehyung is rubbing his eyes, looking around at where he is.
“Where am I?” he seems confused about where he is and who you are.
“Taehyung, why are you in my bed, let alone in my room.” You stand up and make a lot of distance between the two of you. You turn to face the door. The last person you want to look at is Taehyung. Right now, you hate the fact that he looks exactly like Taejoon. It makes you physically ill to look at Taehyung. But before you can dwell on that for too long, Azra is crying. You look towards the nursery sighing. "Anyways, get out of my room and go home.”
He nods and gets out of bed, “I’ll get the baby. Just rest, please.” He’s noticed you refuse to look at him, and he can’t be sure why, but it hurts him a little.
“No! No, I want you to leave, Taehyung. Please.” he moved back into your line of sight, so you turn away and walk to the nursery. Taehyung follows behind you.
“I can leave you alone, but I’m not going. I told my mom I’d stay for the next couple of weeks.” He takes Azra from you, and you move to take him back but are immediately deterred by his face. “You know you’re going to have to look at me eventually. I’m his uncle, I’ll be around…”
You sigh in defeat but still don't look up, “I don’t think you’ll ever understand how hard it is to look at you, Taehyung. It hurts... And I don’t want to cry anymore.”
He scoffs, “You’re not serious, right? I don’t understand? I have to do is look in the fucking mirror and be reminded of my brother. Someone I shared a womb and room with almost my entire life. You’re not the only person hurting.” he leaves with Azra to the kitchen, and you're just standing there. You want to yell at him, but you don’t want to upset the baby.
You knew part of you wished that Taehyung was Sujin and that life was normal. You thought it was unfair that you had to go through this. But he’s right; he isn't the only one hurting. You’d been so selfish with your grief that you weren’t allowing anyone to join you in it. And he was also right that you’d have to look at him eventually, but you'd deal with that when the time was right. Right now, all you want is your son.
“Can I have Azra, please?” Azra coos out a little mama when he sees you, and Taehyung looks over at you and then back to Azra as he feeds him his banana baby food.
“Um, we're having nom-noms right now. Right, Azzy? We’re having nom noms?” Azra giggles, repeating the word, and you wish you could be in his shoes. Living his baby life with no concept of death. You stared at him and realized one day, you’d have to tell him about his father, and tears welled up in your eyes.
“Taehyung, I don’t need your help. I need you to leave, please. You can come over later, but I want to be alone now.” You take Azra out of his high chair and walk towards the den. “We can discuss why you were in my bed after I take Azra to daycare, then you can come with me to pick up some of Sujin’s things from the base. Come back in 2 hours, I’ll be ready then…”
Taehyung reluctantly agrees. He’s scared to leave you, in all honesty. Sujin had mentioned to him about your past struggles with your mental health, but he didn't want to come off as he couldn’t trust you. He wanted you to know he understood what you were going through and was there for you and Azra.
You watch through the curtains as Taehyung pulls out of the driveway and drives off into the distance. You turn back to the living room and look around. You feel… empty. You knew that grief never grows smaller with time and that life grows around grief. It was such a cliche analogy, and it helped you when your grandmother died, but this was different. You and Sujin talked about getting old and grey together. About watching Azra graduate high school and college, get married, and have children. Now, it was just you, no Sujin, to help with the woes of parenting. You, at 25, are a widowed mom of one. You’re going to miss hearing the sound of him breathing when you lay your head on his chest. You’re going to miss the way he kissed you, held you, and made love to you. You would miss the way he would quote Napoleon Dynamite at the most random times. You were going to miss him. Plain and simple. You wish you had time to grieve but couldn’t because you had responsibilities. So you pushed yourself to keep going because of Azra.
About 2 hours later, you pull into your driveway, returning home from taking the baby to daycare. Taehyung is already there, waiting outside, smoking a cigarette. The feeling of annoyance was brewing inside you. But then you push the feeling away because how could you be annoyed with someone just trying to do the same thing you are; grieve. So you get out of the car and join him on the stoop. “Why are you waiting outside? You know where the house key is. It’s the middle of fall; it's cold.”
“I didn’t want to be reminded of him right away.” he takes a drag, handing you a coffee he picked up on the way back to the house, which you happily accept. “Your house smells like him still. It’s weird.”
You nod; he’s not wrong. It does smell like him, but you like that. You didn’t want to forget that smell. “Yeah, I know. It is kinda weird, isn’t it.” you chuckle softly. He smiles at you, and you meet his eyes finally. You feel something weird, something that makes you blush. He looks away quickly, taking another drag of his cigarette as he stands before flicking it. “Let’s go get my brother’s shit.”

An hour later, you finally leave base with the bit of stuff your husband left behind and some paperwork explaining how your benefits will now work. You don’t even care about that stuff, especially because this wasn’t how life was supposed to be going for you. You get back in the car and give Taehyung the box. “I have to go meet with a lawyer about his will. I need a witness so they can open it. Would you like to come?” He nods, and you drive off.
“So why were you in my bed?” you ask, looking over to see his cheeks are now rosy.
“Well, after you passed out from crying, I went to put you in bed and..” he looks worried; he doesn’t want to embarrass you.
“And???” you press.
“And…” He sighs, “And when I went to leave… You confused me with Su, and I didn’t have the heart to stop you, so I held you until you fell asleep. However, anytime I moved, you’d grip me tighter, so I fell asleep with you…” He rubs the back of his head, and you know he’s just as embarrassed as you are. “I know it was inappropriate, but you wouldn’t let me leave..”
“Oh..” the silence that follows is extremely awkward. “Well, thank you for staying, I guess..”
“Yeah, don’t mention it. Literally.” He chuckles.
The drive to the law office is quiet and gives you time to think about what his will could say. It’s strange, though, because he never told you about it. You just assumed when he died that everything would go to you and Azra by default, but knowing he had a will scared you. Because what could he possibly have to say?
“We’re here..” you don’t move, not even to unbuckle yourself. Your hands are gripping the steering wheel so hard your knuckles are turning white. Your heart feels like it’s going to explode. Taehyung takes your hand, rubbing the back of it with his thumb.
“Calm down, nothing can get worse. I know my brother. He’d never do anything to hurt you.” You wished it soothed you to hear those words, but his brother had done something to hurt you. Of course, it wasn't intentional, but it hurt nonetheless.
“Taehyung, your brother has done a lot to hurt me. None of them like this, though. This one he can’t fix with flowers and chocolates.” you say, half giggling, the other half getting choked up.
“Listen, I know this seems like the end of the world, and trust me, it sure as fuck feels like it. But let’s be realistic. You’ll eventually grow to deal with the loss of my brother. You’ll move on with your life, find some awesome guy, and fall in love with him. You’ll probably even get remarried. Realistically, of course.” you just look at him. The way he could say the most asinine shit you’ve ever heard honestly pissed you off.
“Why the fuck would you say that to me right now? I just buried him yesterday. Are you dumb? Please just shut the fuck up until I tell you to talk.” You finally move to get out of the car, slamming the door behind you and mumbling about how much of an idiot he was.
But that was the thing; Taehyung wasn’t stupid. He just says ridiculous shit. In fact, Taehyung graduated cum laude from Stanford, which is why you can’t understand why he doesn't think before he talks.
He sits in the car briefly before coming out and following closely behind you. You two walk into the law office. The receptionist says she’s expecting you and leads you to a small conference room. “I’m nervous…” you sigh, fidgeting.
Before long, a tall, tan-skinned man walked in. He explained the legal jargon and then allowed you and Taehyung time to read over the will. But that's the thing: It wasn’t a will; it was more like letters to people in his life. You found the page for Taehyung and handed it to him. It wasn’t long before you heard sniffling coming from him. You smiled at him. You thought it was sweet how vulnerable he could be.
One page was dedicated to you, telling you all the passwords to his socials and bank accounts, where he had hidden money for Azra, and that he was sorry, but that was all. Nothing else was there. No, I love you, no, I’ll see you again someday, nothing. It was like all you were to him was a vessel to carry and care for his child. To say you were hurt was a complete understatement. But before you could take in the reality of what was happening, you found a page for a woman named Natalie. It describes how much he cared for her but also how much he regretted cheating on you while you were pregnant. He went on to tell her about the life he had imagined with her during their affair, but when you gave birth, it gave him a new meaning in your marriage and that he was sorry they ever got involved. He left her a small amount of money; it wasn’t said for what, only that she would understand what it was for. You only knew of one Natalie; you all went to high school together, but the last you heard, she moved to Los Angeles and hadn’t been back since. There was no way. This had to be Sujin’s idea of a joke. There was no other explanation.
You wanted to know when he even had time to cheat? If he wasn’t at work, he was with you. You try to think of any time he was not with you, but then you remember that he started going to the gym more often during your pregnancy. You thought nothing of it. He was in the military, for god sake. And you held on to that notion until you spotted her walking into the office.
“Hey, what does yours say? Mine tells me to take care of you and Az, and he finally admitted he broke my Donatello figure when we were younger. Plus some other stuff, but that's private.” He chuckles. He must’ve noticed your eyes glazed over because he waved his hand in front of your face. “Helloooo, anyone home?”
“He cheated..” is all you could squeak out. It’s almost inaudible.
Taehyung doesn’t want to believe that you just said, “What? How do you know that? Let me see.” he snatches the papers from your hands and reads them repeatedly. “No way, Joon would never do that.”
“He did, and she’s here. The blonde woman you see in the lobby. Thats her… I don’t think she knows I’m here, nor was I even supposed to read that. I don’t think he meant to put it in there.” You both sit there in silence; before you know it, you’re storming into the lobby.
She looked shocked to see you, like she didn't understand what you were doing there. “y/n, what’re you doing here?”
“What the fuck do you mean what am I doing here? What are you doing here?” You scoff. You can’t believe this lady. She has the nerve to question you like you’re the mistress. So, you do the most logical thing you could do in any law office. You slap the shit out of her. “So you like fucking married men while their wives are at home caring for their children? Huh? Huh? ANSWER ME!”
She looks terrified and confused, clutching her now red cheek. “Married. He told me you two were divorced and that he only wore his ring to keep appearances with his parents.”
“Oh please, you can’t be that fucking stupid. YOU WENT TO FUCKING BERKLEY! You knew; don’t play dumb with me!” You are furious and yelling so loud a crowd is starting to gather. Taehyung comes up behind you, trying to calm you so he can get you outside, but you’re struggling in his grip. “HEY EVERYONE, HIDE YOUR HUSBANDS NATALIE STARK LIKES TO FUCK MARRIED MEN. NO, LET ME GO TAEHYUNG!”
“Nope, it’s time to go,” he says, flinging you over his shoulder.
Taehyung finally got you into the parking lot, but you still weren’t calm. He didn’t know what to do or say, so he lit a cigarette and handed it to you. “Here, it helps with the stress.”
You take it. You hadn’t smoked a cigarette in almost two years, choosing to quit right before you found out you were pregnant. “Thank you,” you say before taking a long drag. The nicotine rushes straight to your head, mellowing you out. “I swear to god, your bother is so fucking lucky he fucking died before I found this out because I would’ve killed him my-damn-self.”
You sigh. Your world is crumbling around you. How could you not have known? And what did you do to deserve this? You never spoke down to him, hell you doted on the mother fucker, and still he cheated. He lied to you every day with a smile on his face like everything was fine. Why couldn’t he be a man and tell you he was unhappy? Why did he have to die for you to find out? You wanted answers, and the shittiest thing, about it, was that you’d never get them.
Taehyung is still quiet. You wish he would just go away because looking at him makes you angrier than before. “Can you turn around or something? Your face is pissing me off.”
“Listen, I understand you’re upset but don’t take that shit out on me. I’m not Sujin, I didn’t do shit to you. Get in the fucking car, I want to go home.” He snatches the keys from you and walks to the other side of the car.
You finish your cigarette and get in. By the time you two make it back to town, you have to go pick up Azra. So you drop Taehyung off at your house and get him. When you left, you told Tae you wanted him to be gone when you returned, but he didn’t listen.

You were too tired to argue with Taehyung, so you put Azra down for a nap and then walked to the kitchen. “You want a glass of wine? I have a feeling the rest of the week is going to suck as bad as today,” you call out to Taehyung from the kitchen.
“Yeah, sure. Can I smoke in here?” he’s walking around the den, looking at all the pictures. He stops on a photo of you two at your baby shower. He smiles fondly. If Taehyung was honest, he wished he was around more. He hadn’t seen you or his brother since Azra was born. And he regretted that.
Taehyung had a secret he told no one but hated you for. At your wedding, you told the story about how you met your husband, but the boy you met that day was Taehyung. He fell in love with you the moment he laid eyes on you. He confessed to you a week later and told you to think about it. When he went to find you the following day, he saw you kissing his brother; the rest is history.
“Uh, no, but we can go into the sunroom. It’s heated, and I have the baby monitor.” You leave the kitchen and go into the den, “Is that okay with you?”
Taehyung looks over at you. He wished that it was him that you had fallen in love with. He would never hurt you in the way that Taejoon had. He felt selfish for his thoughts about you. They were wrong. Especially considering the current circumstances. But if he was being honest, you’d never look more beautiful to him than you did right now. Your hair was messy, with no make-up on, in sweatpants and an oversized t-shirt. “Yeah, that's fine.”
You grab the bottle and some glasses and walk towards the sunroom, placing them on the coffee table and going to the sound system. You didn’t want to listen to the silence. You put on something soft and airy to help soothe your nerves. Your week had gone from bad to fucked up in a matter of 24 hours. Whoever you were in your previous life must have been one fucked up person because your current life is kicking your ass.
“Hey, you guys got it remodeled. I like it.” he looks around, admiring the work.
“Uh, no, I remodeled it. Your brother did jack shit but complain about how it was keeping him awake.” You roll your eyes and throw yourself into one of the many chairs, sighing.
Taehyung takes a seat next to you.“I’m sorry this is happening to you. I know I was giving you a hard time earlier today, but I just wanted you to know you’re not alone. I’m here for you completely.” He grabs your hand. You look down at your hands and then back at him.
“It’s just tough to be around you, Taehyung. Even more so now than before. I wish you would get that, but you’re so goddamn stubborn. And you’re really touchy, it’s weird.” You remove your hand from his and pour two glasses.
He chuckles. “I’m sorry. It’s just how I show people I care. But if it makes you uncomfortable, I’ll stop.” He grabs a glass and takes a sip. He stands to open a window and then lights a cigarette. “Do you have an ashtray?”
You set one down on the coffee table. Taehyung turns to look back at where you set it, and for a split second, life feels normal. Like Sujin didn’t die, you didn’t find out he was cheating, and you felt happy. The silence that follows you is so comfortable. He smiles at you before looking back out the window. Then Fade into You by Mazy Star comes on, and Taehyung walks over to you.
“Dance with me.” He extends a hand to you.
You scrunch your face with a smile, “I’m tired.” you try to push his hand away, but he pulls you up by your hand. You give into the dance eventually, resting your head on his chest.
“I know I’ve said it a lot today, but I’m sorry about everything my brother has put you through… I would’ve never done that to you. You’re way too precious to me.” you pull away to look at him. And he stares down at you. The tension is so thick you could cut it with a knife. And before you knew it, your lips were crashing together.
You both knew it was wrong, but it was like magnets. You two couldn’t pull away. Your hands move to the hem of Taehyung's shirt, sliding up against the smooth skin of his torso. He wasn’t lean, and you liked that a lot, so you scraped your nails against his stomach. “Take this off.”
He takes his shirt off and moves to take yours off. When he finally gets it off, he starts kissing down your chest, “I’ve wanted to do this since I was 15..” You swear you hallucinate him saying that. You unbutton his jeans and slide your hand into his boxers. He moans softly into your neck, and that was enough for him to snap. He tugs your sweatpants down, having you step out of the. He kisses your inner thigh before pulling your panties down, not even allowing you a second before he picks you up and pins you against the window.
Now, to say that Taehyung wasn't gentle was an understatement. He fucked you like he hated you like he wanted you to know how much you ruined his life, but also how much he was willing to give up to be with you. And as much as you knew it was wrong, you loved it. Neither of you talked the whole time. You both enjoy not being sad for once. When everything was all said and done, Taehyung set you down gently and walked away, sitting on the floor. He knew the severity of what had just happened and needed time to process it. But there was no going back from what just happened. You both had effectively ruined each other's lives.
You joined Taehyung on the floor, sitting behind him and leaning your head on his back. You planted a small kiss on his shoulder. You knew everything would be okay when he reached back for your hand to hold. “I’m gonna take care of you from now on,” he says as he kisses the inner of your wrist.
