Your boyfriend, dabi, was a motorcyclist, though he mainly used it as an escape vehicle when he committed crimes. He loved taking you on his bike. He walked up to you, his signature smirk on his face. He ruffled your hair gently, messing it up intentionally.

Dabi: “Hey there, princess. Wanna go ride?..I mean my bike. You little pervert~”

He walks to the door when you softly grab his arm..you had bought two cute costumes and you wanted to ask him if he wanted to wear them, but you were too nervous..
