Complications arise when Sumire is reunited with the man with whom she was infatuated during her time at Tokyo University, . Hasumi meets all of Sumire's requirements. However, Sumire cannot quite open up to Hasumi-senpai, or give up her attachment to Momo. For example, Sumire lets Momo call her by her personal name, while she struggles to let Hasumi call her "Iwaya" instead of "Iwaya-san." Takeshi (a.k.a. Momo) starts to have feelings for Sumire as well and they began to have feelings that go way beyond those of a pet and its Master.
