Cang and Mingyu are back in the men's room, but Mingyu is still wearing his girls' clothes. Mingyu asks why they're still dressed as boys, and Cang tells him that the performance of the class is tied to the number of points that Mingyu scores in the class. He says that if Mingyu can't swim, he'll have to go back to his "true selves" in another class as well, which Mingyu doesn't think is a good idea, since they'd be suspicious. Aww, Mingyu says, he thinks Mingyu's been absorbed in grief, and he's worried that he won't be able to keep up with Mingyu in the future. He tells Mingyu to hold back, because he wants to go swimming with a "bare butt." Mingyu tells him not to worry, because Mingyu has a waterproof system to keep him safe in the water.
