Lee Jin-yeon and Jeon Seong-seung are talking. Jeon says that he's been made a villain, and that he doesn't know why Lee didn't ask him to be his friend. He's back at school, and he tells Lee that he likes the rooftop too, but that he can't be friends with Lee because he likes his dead friend. Lee says that they stole the key from the teachers' office, and copied it to the other students' lockers. But that's not enough for Jeon, who wants to know what's inside.
