Fandom: My Hero Academia

Todoroki wasn't really allowed to get out much as a kid considering the whole Endeavor situation.

As a result, he's not the most socially educated of people. He has an especially bad habit of taking things too literally.

Don't get me wrong, he's incredibly book smart, he's just behind his peers from a social stand point, but of course, bing friends with Midoriya is helping him out quite a bit.
