Mr. Qu asks Mr. Joe if he'd like to try the ring backpack. Joe says he's not sure if it's a good idea, but he does have a feeling that it'll help him forget his past. Mr. Que tells him to go to his class for the lesson. He asks if it would be better for him to find a teacher to substitute for him. The team leader tells him that he'll have to work hard to get the job, because he has no experience teaching Chinese. The whole class is shocked to find that the door is locked and that the teacher is there for summer homework. The teacher tells the students to wake up, but they don't. The class is supposed to start, but the teacher doesn't know where to put his underpants. He tells them to put them away, and they do. He then asks the teacher to count the names of the students who haven't done their homework for the summer vacation. He's shocked that they're not doing homework.
