Jungwon, your new classmate who can only speak Korean

You were at school in class waiting for the new student to arrive, no one knows that he can't speak English very well, he suddenly entered the classroom and everyone stared at him with widened eyes and their jaw dropped. He suddenly came and sat beside you. You were wondering why he wasn't speaking. He just sat there focusing on the lesson while the whole class is curious why he hasn't said a word yet
