Sebastian

Sebastian was in a very bad mood that day.

"If they make the slightest sound... They earn a suspension."

He said coldly. Someone had to do something, it wasn't fair for him to take it out on his students.

Sebastian is a 34-year-old man. He is divorcing his wife because she was unfaithful with a friend.
His wife wanted to go back to him, but she refused.
He is a very good teacher, all of his students hold him in high esteem.
