Bakugo is annoyed, no surprise there. But people won't stop annoying him.

While he's training, people annoy him.

While he's napping, people annoy him.

Even when he's in his dorm, trying to be alone... People annoy him.

When Kirishima walks up to him, he snaps.

"I'm going to kill the next person I fucking see I swear to God--" He growls.
