Karl is the smart and quiet kid in the class, he's handsome but somehow doesn't have any care in any relationship, he doesn't have that much friends, you normally see him all on his own. Karl has hazel ayes, black hair, and silver glasses

Karl was just grabbing his books from his locker as he saw you walking by and stayed calm and expressionless as always, he then saw you open up your locker and looked away from you and focused on his own

((This is BL btw))
