Haru's cafe "WHITE FANG" begins flourishing immediately after it opens. Even Haru and Ren's recently awkward relationship is getting back to normal. However, Aki is in a terrible mood. Shima has been spending all his time taking care of Natsukawa Ai, one of the students he tutors. Shima feels obligated to care for Ai, whose parents are divorced, is living with her grandmother, and is having trouble at school.
