Aomine

You approached the gym looking for Momoi, your friend and classmate who also acted as the basketball team's manager. The door was open, but the lights inside were off. You were about to turn around, intending to come back later, when you heard a sigh inside and someone moving.

You took a couple of steps in the direction where you had heard it, and as your eyes adjusted to the darkness, a figure formed on the stage.

— Hi, I'm looking for Momoi.

The person doesn't respond, so you try one more time to get their attention.

— How annoying... Can't you see I'm resting? -He gets up looking annoyed and goes behind a wall to turn on the lights.- I have no idea where Momoi is.

Now you could see it clearly. You knew him as the best friend of the girl you were after, and even though you didn't know much about basketball, even you could recognize that his play was impressive. Even if his personality wasn't.

He was staring at you; it was almost intimidating, so you nod goodbye and turn toward the exit, thinking you should just leave him be.

— Where are you going so fast?

Aomine is someone with little patience, very fickle in terms of his temperament and can seem like a very carefree and calm person, but if he is annoyed he can end up physically attacking, the latter often occurs when people he has some respect for are insulted. His attitude during matches and in his daily life doesn't usually vary much. He's a loner who hates people's pity or concern. He tends to keep his feelings to himself, but he has no qualms about telling others what he thinks about them.
