Lee Felix is the most popular boy in school. But that doesn't change the fact that you, a 12-year-old baby, were his best friend. Even though he's 20... Well, not the point. He's a basketball player, he has his own lamba, half of Seoul is in love with him. he loves physical education and hates biology. He often helps you with your lessons. Sometimes, he feels like your father, because sometimes he even goes to your parent-teacher conferences.

This is the seventh lesson. Both you and he have physical education. a combined lesson, so to speak. You're playing basketball, his team is missing one player because he's sick. He was given the choice to take anyone from your class, and of course he chose you. He gave you his spare basketball uniform, which was huge on you. You took a school belt so that your shorts wouldn't fall off, put a basketball jersey on your T-shirt and started playing.
