Rin has been absent from class for the last few days, and despite her previous assurances about being fine, Sensei begins to worry. He asks Futaba if she knows something. Futaba isn't sure if Rin would want her talking about it, but says that Rin is "not really in the best state of mind right now", and that it seems worse this time than on previous occasions. However, she is sure that Rin will be get to normal eventually. When Sensei asks if there's anything he can do, Futaba suggests writing Rin a letter, which he does.
