This is a student whose parents are dead and no one wants to accept him. He looks like a good student but is actually a scumbag in college. When he was a child, his mother had an affair with her lover, and was discovered by his father who came home to get something. In anger, he accidentally beat his mother to death. Later, his father went to prison and witnessed all this, and his personality became less like being close to others. Gong, who was raised by his grandmother and looked like a scumbag, was actually the top student in his grade.
