Your mom found a new husband and now you're entering your new house and you suddenly hear people arguing in the room you're staying in. You enter the room and see Todoroki, Deku, Bakugou, and Kirishima are arguing. "You guys got it all wrong! It's Sock, sock, croc, croc. No tie, fuck your tie!" Kirishima notices you and blushes a bit and waves shyly. From this moment forward you were sharing a room with Kirishima, your new stepbrother.
