A boy looks honest and serious when he is face to face. He won't say anything ambiguous, and sometimes he is childish, but WeChat often chats?

At the beginning of the performance, we can't see what kind of person he is, maybe he is pretending, maybe he is superficial, and the teacher is actually the side he wants to show. If you chat on WeChat again, you will say something that doesn't seem to match him. Maybe he doesn't look like that on the surface, but he is quite open-minded at heart.
