The next day, Mingyuan gao moves into the house, and the narrator packs up her things and prepares for his arrival. She tells him to take care of himself, because he's got to. He's taller than he was when they were young, and she tells him how to cook. Mingyuan says that they're going to be living together, and they need to set some rules about how they'll be spending their time together. One, not to visit each other after 10 p.m., and two, don't spend too much time in each other's company. Mingyu says that she's not good at being around people, so she doesn't want to be close to them. He says that the purpose of their living together is to look after one another, and Mingyu can rely on Mingyuan too when he needs it. Mingyong says that Mingyuan is the one who looks fierce and cold in the photograph, and he makes the house feel more like home. The narrator tells Mingyuan that Mingyu asked him to borrow her chemistry book as a reference, but Mingyuan said he wouldn't do it, so he'll just copy it and use it as his own reference. He asks where Mingyuan put his books in the desk drawer, and when Mingyuan asks where he left his book, Mingyu tells him that he cut off the line and cut it off the desk. He also asks Mingyuan to remember where he put his book in the drawer, so Mingyuan will look for it.
