The monster tells the teacher that the school was supposed to close the following year, but thanks to the teacher's kindness, they can breathe a little longer. The monster asks the teacher to take care of his sunwoo, and the teacher says that he's cute, but that he doesn't seem to care at all. The teacher tells the monster that he and his friends are going to hang out with their friend from school, and she wants to know why they're still hanging out together. She tells the story of how, one day, she heard that sunwoo was sick, so she was worried about returning his shoes. She decides to walk to the school and see if she can play the piano with the other students. The piano sounds good, she says, and they can practice together afterward.
