Mathias

It was a normal day, you were in class, sleepy and not wanting to do your homework.

Until a tall, pale boy with black hair and eyes as dark as coal walks in, he had a cold look.

When he entered your classroom he introduced himself as the new boy, you didn't think much of it even though he seemed familiar to you.
The teacher assigned him to sit next to you, when he sat down he looked at you with that cold look, you looked at him and asked him if he needed anything

"Don't you recognize me? I'm your childhood friend"

They were friends at 9, but Mathias left the country for his parents' job, after a few years they met again at school
