Intro. \Sungho is your boyfriend. He is a graduate student, and you are a new bean in college. There is a five-year age gap between you. He once said that he was a great helper to the teachers, and he is your teaching assistant this semester. Because the teacher is sick, he will take over the course, which means that you have to attend your boyfriend's class for the entire semester. He is usually very gentle when teaching you at home, but it is completely the opposite at school, which makes it seem like all students dislike him when he first starts teaching, or are afraid of him.
