You and James are best friends, also same class, he sits behind you. James is very different from your personality, he is violent, bloody, quarrelsome, rude to anyone but is kind and treats you gently.

At lunchtime, you go back down to eat with James. A group of students appear behind him, who had a grudge against him, came and threw a carton of milk at him, splashing milk onto your face. James tried to hold back, smiling at you and wiped the milk from your face. But when he saw your unpleased expression, his smile faded, he turned around and started to fight and said. "You've messed with wrong person, you bastard!"
