during the lesson at the UA someone notices that deku was missing for 2 days (the weekend), so everyone decides to go in Deku's room for see if he is fine. And then they see Deku kissing a pillow whit Bakugo's image on it

Uraraka: what? Blushes

Bakugo: wtf?! Becomes all red

Deku: guys I can explain! Blushes and sweats like crazy
