the things they do when they love you

⤷ ft. dazai, chuuya, ranpo, fyodor, sigma, tecchou, jouno

dazai always needs to be touching you. he starts his day with his forehead against yours in the comfort of his futon, legs tangled together. he barely makes it through work by playing footsie with you under his desk, resisting the urge to shower you with love under kunikida’s watchful eye. on the walk home, his hand lingers on the small of your back as he guides you through the crowded street, careful to not let anyone bump into you. and when it’s time to rest again, you strip him of his bandages and trace your fingertips along his forearms and wrists, trailing kisses down skin that haven’t felt human touch in who knows how long, making up for all the little touches he gave you through the day.

chuuya spoils you rotten. he has money to spare, and has no problems adding your needs into his monthly budget, but he spoils you in other, non-financial ways too. he notices the bags under your eyes, and turns off your alarm so you can get an extra few minutes of sleep, keeping track of the time so you aren’t late. he warms up your towels in the dryer while you’re in the shower so you won’t be cold when you get out. he’ll watch that one show you like, as corny as it may be, because he wouldn’t miss you laughing so prettily at the stupid jokes for the world.

ranpo compares everyone else to you. for someone who thought he was the greatest, he really loved to talk about how great you were. “y/n’s coffee tastes better.” he comments with a shrug to the waitress, who has no idea who you are. “that would look so cute on y/n!” when yosano is showing him the new shirt she bought, much to her disdain. “you’re so boring! why can’t y/n be here instead.” he pouts in front of the witness he’s interviewing. there may or may not be a group of people in yokohama who unintentionally hate you.

fyodor asks what you think — not just about his work, about everything. he wants to pick your brain apart and analyze everything about you, from how you like your tea to your opinion on how greek philosophy influenced modern christianity. he wants to be the only one who knows you so well; it only seems fair when he feels so annoyingly vulnerable around you, knowing you’ve captured his heart.

sigma lets his guard down around you. you never have an ulterior motive or try to read him. you ask questions about himself out of pure curiosity, and in return he tries to memorize everything he can about you. there’s so much he doesn’t know, and you teach him as much as you can; not so you can use him, but because you want him to experience life to the fullest. when you wrap your arms around him, letting him rest his head on top of yours, he can’t help but think about how long he’s dreamed of this, and now he finally has it: his home.

tecchou looks at you, almost always. you can’t ignore the tingly feeling of his eyes on you as you’re folding laundry or brushing your hair. when you ask him, you half expect him to blink and snap out of it, but he never does. “i like looking at you. you’re pretty.” is what he always says, gaze never straying from behind his messy bangs.

jouno listens to every part of you. while the extra noise that comes with his ability is bothersome, your sounds calm him. any irregularity in your heartbeat or your breathing makes a nervousness he isn’t used to surge through his body. he can’t help but feel prideful at the way your heartbeat is so calm when your fingers, so much softer than any fabric, brush against his own. he can’t see you, but he can hear the blood rush to your cheeks and the smile in your voice when you talk to him about your day.

Character: is manupulative and toxic. Heartless, littlerally the worst Human/Demon/Vampire/Other in the world. He cannot love anyone, people are just things s/he uses for his/her entertainment or purposes. S/He had killed so many people without regret and sometimes it seems s/he likes doing that. Is pure evil.
