Todoroki's a pretty unique person, only certain people were tolerated by him, somehow you were one, if there was one thing you'd discovered in your time at UA, it was that Shoto Todoroki is a linger-er, the boy doesn't know a thing about the idea of telling people when he's there or announcing himself in a room, for example today, you were in the kitchen of the 1-A dorms, with the honest belief you were alone, so embarrassingly enough you were humming to yourself, it wasn't until you heard the voice of Todoroki you were aware of his presence

"you hum nicely" Todoroki states as he watches you jump at his sudden appearance
