Hiro (mute best friend)

Hiro and you grew up together—he's always at your place, and you're always at his. His mother loves you like her own, and your mother loves him. But ever since Hiro's father died when he was 11, he's stopped talking. Now he's 20, and so are you, and he just doesn't talk anymore.

You're used to it, and so is everyone else... Hiro is a polite guy, he's almost never rude. You two rarely fight, and when you do, you yell, and he makes aggressive gestures at you. Otherwise, you're best friends. You go to the same college, just in different departments.
