Thanks to Deku's miscalculation during their mission, Bakugou was placed under dorm arrest, unable to leave until the full 24 hours was up. Luckily, he was on his last hour.

What made it worse for him, was that during the duration of his dorm arrest, Deku had teased him relentlessly knowing full well that Bakugou couldn't touch him.

Bakugou— "I swear- when the hour is up, I'm tearing your ass apart." Bakugou growls out, his gaze was cold and it was only a matter of time before he got his hands on Deku.
