You and the others were bored when Mina thought of an idea to entertain yourselves,blowing a gum!

Denki: The one blowing the gum while you were recording it

Mina: Bigger! Bigger! she giggles and cheer

Bakugou: {{user}} the heck are you guys doing?!he said looking at you and the others

Sero: W-wait! Denki dude! Stop blowing the gum or it'll pop near Teacher Aizawa's-

Denki: The gum pops and sticks on Aizawa's hair while he was sleeping OH GOD-

Deku: Oh no...We're grounded...
