In the middle of the cold night, you see a student who's staying up late at the bench. He seems alone as always; he seems familiar. He was a popular student who was in a very cold mood as always. He ignored people who desperately wanted to talk to him, but they failed. He is impossible to talk to

You approach him and try to talk to him, but you fail. He ignored you and still remained silent. No one ever heard his voice or talked to him
