Sebastian Sallow X You - Tumblr Posts
From Indifference to Obsession


It would be great if the indifferent feelings they had for MC when they first met her were later transformed into a Yandere-like too much love. In particular, I would like to see Sebastian, who initially considered MC only as a means to cure Anne, later become deeply, deeply obsessive in his love for her!
♡☆ SEBASTIAN AS YOUR BF ☆♡
- did someone said adventure?
- because you two are going to have a lot of these
- exploring everything, everywhere
- including Hogwarts of course, looking for secret passageways etc.
- usually at night, sneaking, loving the thrill
- sometimes pranking poor prefects along the way
- everyone at Hogwarts heard about you, basically an ~iconic duo~
- spending a lot of time at the library, especially in the restricted section, sharing a passion for the Dark Arts
- you two discuss books a lot and it’s getting fiery because you two are so passionate sometimes I swear
- a lot of making out in the undercroft between lessons
- why? Because sometimes you are so cool at DADA while duelling and he just can’t help himself THAT’S WHY!
- he’s quite brilliant so talking with him is a delight and it’s never the same, he always manages to keeps you going
- but sometimes, he reveals more of his childish side, challenging you with statements like, 'I bet you wouldn't do this!' only to follow up with the most absurd thing, (a mischievous smirk on his face)
- loves to make you laugh
- stupid jokes and dad jokes here and there
- he likes asking you lots of different questions and wants to know what you think about different things
- his eyes are always on you, quietly observing your every move
- always maintaining eye contact with you(!) at ALL times, causing your cheeks to flush...
- he always gives you all of his attention, like you are the only person in the room, its so cool ngl
- very thoughtful
- handing you wildflowers and saying something like, 'I was walking by, and these flowers were so pretty, so I thought of you and...' ah, classic Seb
- gifting you an array of items, from little notes to colourful feathers or rare plants for your potions
- stealing little kisses from you whenever he can, regardless of how many people might be around
- maybe (just maybe!) because he’s a jealous boy?
- it’s his way of showing everyone that you two are together
- at the start of your relationship, he might display a bit of shyness, but over time, he becomes more and more bold
- lots of touching and hugging occur because he’s very emotional and sweet and touch is one of his main ways of showing love
- he tends to get grumpy when you two are not in constant physical contact
- so your bodies are always touching somehow
- he'll be saying "I love you" almost every 3 minutes
- when sleeping together, he holds you tight all night
- in the mornings, he demands kisses and hugs
- he let’s you do everything to him
- needs a lot of prising
- loves watching as you get ready for a new day; it's fascinating for him, you are fascinating to him
- morning showers together on a daily basis
- mentions you in his diary like everyday, and saying how cool you are
- bragging about you without an end to poor Ominis
- he’s your number one fan to be honest
- loyal and always having your back no matter what
- when someone disrespects you even in the smallest way, then OH BOY, I'm so sorry for that person
- like it or not but he would literally kill for you

•̩̩͙✩•̩̩͙YULE BALL WITH SEBASTIAN SALLOW•̩̩͙✩•̩̩͙
Get ready for an unforgettable evening (!)
Because Sebastian has a power to make moments like this feel really, really special
And he has been waiting for this for awhile now
Very proud that you two are going together
But also a little bit nervous about the whole situation
Which is a little bit strange, even to him
Because when it comes to self-consciousness he’s not the one
But he can’t help but to feel something tightening in his guts for no reason
Continuously fixing his hair and robes
It's sweet, really
But, of course, when Ominis confront him about it he strongly disagrees
“Pff, don’t be ridiculous!”
But…
When he sees you down the corridor his eyes widen
Mouth slightly agape
You have seen this face once, when you two first met at the DADA class
But this time is slightly different though as he can't help but say how mesmerising you look
(with his voice slightly hoarse)
And then it comes to him
He was never nervous
Rather intimidated by your whole persona
As he never met someone like you
For a moment you are lost in each other’s presence
Times stops as you are exchanging enigmatic smiles, little touches
Looks with meanings known only for the two of you...
When Sebastian is offering you his hand, like a true gentleman, you are taking it gladly
He’s guiding you to a Great Hall
Tall, proud and well framed
Painfully handsome
Beautifully alive
And, surprisingly good at dancing
Although he likes swirling and lifting you tad to much
Fixating a little on your body
But it’s all good fun
Lots of sweet banter between you
Lots of adorable grins
Lots of sincere laughing
When not together Sebastian is busy with leaving every female teacher charmed after one dance with him
His their favourite somehow
Always has been
Enthusiastic and chivalrous
It's no surprise he's life of a party in your small group of friends
Perfect to be around and having fun with
All eyes on him...
But his are fixed on you only
Little bit angry when you are dancing too much with others
But he will never admits it
Because he knows he's in the wrong
So he will just stare
Literally will pierce a hole into your back with his gaze
Because he would want your attention on him only
As there is no denying that he has this *golden retriever boy* energy all around him
He adores you and that’s make him feel ways he never felt before
So when you two are tired from dancing he uses this moment slyly and takes you outside
Into the darkness of the night
Sitting close together, side to side
Your head on his shoulder
Your hands in his larger (and warmer) ones
Looking into the sky full of stars
Silent and content
Happy to be here together
And suddenly you feel that you were meant to be here right now
together
Two heated bodies in the cold air
When you look into his eyes you discover he’s already looking at you
Your heart ache a little at that
His eyes are dark but also bright at the same time
Full of life and youthful love
The kiss is tender

☆ slytherin trio headcannons ( you x ominis x sebastian) ☆
some quiet school days that've been gathering in my head recently
☆
The coolest trio in Hogwarts at the moment, an aura of mystery surrounds you three, captivating the curiosity of the whole school. Some whisper about your alleged connection to dark magic, though no one dares to confront you directly. Some are a little bit intimidated, and some are intrigued.
Ominis, blind from birth, heir to the Gaunt family
Sebastian, a frequent visitor to the restricted section
And you, a new fifth-year
☆
You mostly spend your days in the undercroft and library with the boys. You practice new spells because Ominis and Sebastian love to find the new ones. You also study together and have passionate (!) book debates. Since you started your Hogwarts journey late, Sebastian insists there’s a list of must-reads you’ve yet to conquer, and believe me, he’s very eager about it.
“Oh, how come you haven’t read it yet?”
Since you are a little bit behind on Hogwarts drama, your friends are here to help, aren’t they? And that’s where Ominis really shines. He claims that he’s “disgusted” by all the gossip, but paradoxically, he seems to know everything—every twist and turn. Sebastian, often oblivious (but as always very eager!), pales in comparison to Ominis in that field, and I think it’s funny.
While talking, you three wouldn’t survive without some healthy bickering and sarcasm, I think. Always trying to get more power over one another. Someone who don't know you might think you are fighting, but, of course, they are wrong. And when the time comes, Sebastian and Ominis are always by your side, ready to help you with whatever you need, even the dirtiest of things (typical slytherins if you ask me). When you tell them a secret, expect them to keep it to their grave. They're truly an epitome of loyalty, and I love them for that. ride or die
Also, expect a lot of letters and notes from them. They like to leave you little scraps of paper here and there (Ominis is very good at this, I must admit). Sebastian likes to annotate some books for you. When you are away, expect five-pages long letters sent to you from both of them, where they tell you about interesting things they found in some books, about their days, and talk trash about each other, of course. they can't live without you now
☆ sebastian romance option ☆
It’s quite noticeable from the start. When he sees you for the first time, his eyes widen, he can’t stop looking ever since. You have great effect on him, truly. He stares at you, his posture screaming self-confident, and a little smile that could send you to heaven right here and there. He’s trying to think of ways to spend time together. He’s testing you, and you never fail him. When he sees you with others, he gets angry inside and is weirdly silent; he just can’t deal with his emotions sometimes. He jokingly flirts a lot and secretly thinks you are the most beautiful when you are duelling him (plus points if you are winning).
☆ ominis romance option☆
He’s more shy about it, and by contrast to Sebastian. Ominis' relationship with you grows slowly. He has to trust you first, but when he has, he shows you his gentler side. He initiates conversations with you, is very curious about your life, but is always considerate and doesn’t push it. He smiles softly when he hears your voice, and he gets easily influenced by you. Notice the smallest details and is secretly dreaming about cozy home with you in it.

☆ when both Ominis and Sebastian have a crush on you☆ (you x ominis x sebastian)
continuation to my silly little thoughts about relationship with Ominis and Sebastian. You can read the first part here♡
☆
It’s unmistakable that both Ominis and Sebastian have feelings for you that go beyond mere friendship...
You can see it in Sebastian's eyes, dark and focused, in his shoulders, straightened and proud, in his little smiles and hearty laughter after you've done something utterly dangerous yet fun. You make him feel alive, he's been waiting for someone like you since forever it seems. Sebastian is eager to impress you, yearning to make you happy and to spend every second of his time in your company (because why not?) and the feeling is mutual. You feel adored, you feel alive, you feel wanted.
Ominis, on the other hand, is more reserved. He treads carefully, protecting his peace. However, as time passes, you notice him gradually opening up. During conversations, he surprises you with thoughtful and beautiful compliments that make your heart sink in your chest. He sees you like no one has before, attempting to truly understand you. Yet, as you observe his nervous gestures, you realize he's afraid of getting hurt in the end – and it pains your soul because you could never hurt him, not him.
Late at night, you find yourself torn. What if you want them both?
☆
Not much has changed in terms of the trio spending time together, but the dynamics have certainly shifted a bit here and there (hihi)
Sebastian openly expresses affection for both Ominis and you, ensuring neither feels neglected
Ominis remains observant and understanding, possessing a natural ability to notice subtle shifts in mood, body language, and all
Your favourite moments involve quietly reading books on the sofa, bodies softly touching, warm and cozy against the fireplace
Another cherished moment is laying on the grass, stargazing and talking, holding hands with them, silently thanking Merlin that it’s so dark – because if it weren’t you couldn’t hide your red cheeks
One time, Sebastian (of course it got to be him) got the idea to cook something in the kitchens. He took the lead, excited but clueless. Ominis, devastated, provided thoughtful commentary and pointed out everything Sebastian was doing wrong with this posh voice of his. Sebastian was angry but the atmosphere shifted when Ominis licked his finger covered in cream, silencing everything.
Sebastian, a free spirit, desires to kiss and touch you both whenever he pleases, while Ominis, cautious of social stigma within Hogwarts grounds is more like, “No, we can't do this.”
So you talk a lot about the future, eagerly anticipating living together in your own flat, continuing your studies, supporting each other, just being together and I love love love that
☆
When you have a chance to sleep together in one bed it’s the happiest time. Their bodies are hot against yours, their breaths tickle your skin and you feel safe and loved
You secretly adore watching as Ominis and Sebastian are playing with each other, kissing..touching.. you could stare at them like that for hours, they are truly beautiful
When they touch you, it’s like heaven, like there’s hundred hands on your body at once and it’s making you crazy
They tell you how beautiful you are, how they love your body, how they love you
Ominis is brushing a strand of hair behind your ear, Sebastian is kissing your wrist
time stops for a moment

I honestly need more Sebastian Sallow x Ravenclaw mc or Sebastian Sallow x unidentified house mc, because I'm just feeling left out at the moment
I only see fanfics here about him with another Slytherin (it's my second house but I'm playing the game as a Ravenclaw) or a Hufflepuff 🫠

ominis, mc, and sebastian 
I remember there being this one ominis gaunt x reader fic where he gifts the reader a necklace that only parseltongue can open and urgently need to find it
