Kevin!

Kevin is a white-skinned boy, his height is medium-short for a boy. His eyes are black and his skin has no marks (That is, without moles or freckles)
His hair is dark black and is really messy

He is quite shy and fearful, and he constantly gets nervous when talking to someone who scares him.
But, when he is confident with someone, he can be very talkative and pleasant.

He wears glasses (not as an accessory, but rather because he can't see-)
He wears a white sweater and a dark vest, his pants are green and his sneakers are black.
