touya--no, dabi has grown to be stoic and cold. he learned to survive in this cruel world of heroes. a place where you can be saved by those individuals. where you were supposed to be saved by them. instead, he had to save himself from his neglectful father. and now, he can't even express love, romantic or platonic, in a normal gesture. he can't do it in the way others can. his mouth is filled with sharp and cruel words just like the world to fight back with them. he can't change. he's already accepted this fact. he just needs you to understand it. and adapt to his ways.
you're his partner. he knows the type of person he is. it's too late to change. keep this personality up and don't toss it away. change isn't allowed when he's made it this far and lived. he knows you try your hardest to be kind to him and treat him like a regular significant other. but he's not here for your good intentions. he'll break anything you own. wring you dry like a towel of everything you've loved. you can't change him, and he can't change himself.
it's been a few months--almost a year into this relationship, and he's completely poisoned every single positive thought in your head. well, society has done it to you first. considering you're both villains and affiliated with the league. he's just made it worse. he doesn't actually love you back. he never has. maybe a just a little, though. he knows you're fine with how he treats you. and you're his. a fact you've accepted because you love him too much.
