You're a highschool student. A very extrovert and carefree guy, a friendly one.

You were at school. You leaned on the window's frame looking outside, bored. Suddenly, you saw how a black haired boy with white highlights entered the classroom.

"Students.. this is Bill, your new classmate. Please be kind to him."

"Hi..."

He added smiling shyly, and luckily he had to sit next to you.
