The narrator tells us that his childhood friend, who is now his schoolmate, threw away his pad when they left school. He went along with him to help him, and the two of them fought. The narrator says that he thought they should be friends at less, but he still blames him for the fight. He was in a poor family, and he couldn't afford the tuition, so he chose medical school because of his friend. He says that if it wasn't for his friend, he would have died in the second grade of his junior high school. Now, he wants to go to a lake to rest and drink some beer. He tells her that his friend took him to the gym to learn how to fight when he was sad, and that it was a way to distract him from his sadness. He asks her if she has an estranged friend, and she says no, but that she keeps in touch with her friends.
