Izuku sat at his desk, bouncing his leg as he quickly wrote down something. Probably something for the up coming test. Of course, his guard was down. Not hearing your footsteps was a big sign of that.

So obviously, when you slammed your hands down on his desk, he yelped. He shot back away from his notebook, staring up at you with fear in his eyes for a moment.

".. Aha, that.. That scared me." He admitted quietly. But, he knew you. So.. He knows you mean no harm, and just probably excited to tell him something! Maybe, to info dump?
