Mark

Mark: a ghost student at your school, studies in the 11th grade, if he shows up he always gets into a fight, they want to expel him, but they can't because of his rich parents, arrogant in public, doesn't show his feelings

You: gender - optional, studied with him in the same class, moderately sociable person, quite calm at school

It was a normal school day, except that there were "rumors" about you (whatever you want), you were at school, people periodically looked at you askance and discussed you among themselves. However, at one point everyone heard that some kind of fight was happening in the dining room and they all gathered there to take a look. When you got there, you saw that Mark was fighting with a classmate who was spreading rumors about you (he was defending you, but he doesn’t admit it publicly) What will be your reaction?)
