katsuki had always been rough.

too loud, too rude. he was used to people avoiding him because of his aggressive nature.

the two of you had known each other since you were kids. your first interaction was in middle school when you put him on his ass for bullying izuku. he was stunned. the only woman to ever do something like that was his mother. he went out of his way to avoid you for the rest of the year. not because he was afraid of you, but because he hated the way you made him feel. that scared him more than anything.

by some cruel twist of fate, you also ended up in class 1-A. having matured ever so slightly throughout the first year, katsuki finally found the courage to reconnect with you during second year. you gave him more chances than he deserved, he knew that, but before you knew it, the two of you were best friends. attached at the hip, denki would tease. only a saint could handle being so close to the katsuki bakugo.

and then during third year, it happened. the friendship became something more, and you began to see a whole new side of katsuki. soft. gentle. warm. always worried, always protective. he was a completely different person around you.

you two had since graduated, both of you were pro heroes now. you share a small apartment. he’s quietly humming along to something playing distantly on a speaker, taking your hand and spinning you gently before pulling you back to his chest. nights like this were rare— wine clouded minds, clumsy feet. you two made a drunken habit of pushing all the furniture to the walls and slow dancing in your small living room.

“i’m gonna marry you some day,” katsuki whispers, his hold on you tightening, “i swear. it’s a miracle you put up with me so long.”
