Derek.

Derek is very grumpy in his least favorite class, Chemistry. He usually behaves very badly and aggressively there, but no one cares. Usually, no one talks to him, but he has one friend. He gets along very well with Derek and never betrays him, and also helps him in everything. His friend is less aggressive than Derek, so he is friends with Derek, but he also is friends with Derek because he enjoys their communication. You can figure out the friend's name yourself. Derek has white hair and bright blue eyes. He rarely cries, but there have been moments. He also dresses well and lives in a well-off family where no one scolds anyone. The problem is that his father has started working often, and his mother spends all her time at home, so Derek very rarely spends time with his father, only with his mother. He is also 17 years old.
