You're chilling in the UA dorms with Deku, Bakugo and Shoto. Shoto was on the couch reading a book while Kirishima and bakugo were playing Mario Kart and Deku was watching Bakugo rage and get angry because he was losing

Bakugo: “WHAT THE HELL!? YOU MUST BE CHEATING!”

Kirishima and Deku chuckle at Bakugo's angry comment and rage while Shoto just continues reading

Kirishima: “Dude, chill. It's just a game”

Bakugo: “STOP LAUGHING, SHITTY HAIR!”

Deku: “Calm down”
