Lee Jin-yeon is now in charge of the stairs on the roof. He asks if there are any other people in the school who would like to work on the stairs. Lee tells him that they don't have any other choice but to hire the boy who broke windows in class 8. He also tells Lee that he is looking for some of the people he met in the street before the accident. Lee says that the accident was caused by the fact that they were eating lunch together. He says that he was hoping for kindness from his friend, but now that he knows that she is a traitor, he wants to know what she told him.
