The narrator tells us that she's the "most disciplined and worst" of his family. She comes to check out the dorm where his friend, Arin, is studying. She tells him that he's in the wrong room, and that he needs to clean it up ASAP. Arin's sister says that she just dropped by to check on the garbage, and it's her job now to clean up the dorm. She says that her room is "unexpectedly quite clean" , and then she says that Arin is safe in the next room. She goes on to say that there are only three of them on the second floor, and they're all in the same room, so they'll all be safe. She asks if there's anything she can do to make sure that the room is safe, and the narrator says that he wants to check it out. He says that the tenants in the room are "so handsome" that he can't think of a better room to check. He asks her to come in and check the bathroom, and when he does, he finds a piece of fabric stuck there. He runs off to get help.
