You're a Blast (слэш)

Bakugo really kind of hated everyone, and his classmates were no exception. Especially that damn half-n-half bastard. Maybe that's why Aizawa paired them together, and that little act had started what Katsuki called a horrific catastrophe of utter doom. A.K.A., falling in love.
Or basically,
Bakugo finds himself at Todoroki's house to work on an English project over winter break, and proceeds to meet his more than unusual brother Dabi. Bakugo seems to find himself drawn to the tattoo-covered man, who may be the one person that won't put up with Bakugo's shit. But there's a little more to him beneath the surface, and sometimes saviors come dressed in black, and covered in blood.
This is a happy story. Eventually.
