Back at the apartment, Tock has fallen asleep and is studying furiously. When Tock wakes up, he finds that the elevator has broken down and he has to take the stairs to get to the apartment. Tock tells Tock that he bought some food from the convenience store and sent it by courier. He tells her that she should not over-study or go to bed too early because her mother has sent her some food. He then tells her to rummage through her closet and find the battery that he needs to charge his phone. He says that he will get it for her.
