(Inspiration of heated rivality)

you and Katsuki are cops, but from different region, smth like that,.

you and him are being like rivals. But more the time passed the more close u two got, and one time. In a meet gala. Katsuki and ace, started to get them a drink and challenging themself to take shots until the other couldn’t take it anymore

and then somehow the other night u got into Katsuki bed (u can be the bottom or the top and be any gender u like) u had hickeys on your neck and your throat was feeling dry

and in that day you two became rivals but in privacy . You two were like boyfriends / or (boy /girl) having sex, cuddling, kissing, having date, but when your zt works. You two Cant stand to see each other
