His missing father, Goro (Katsumi Takahashi), has returned with a mysterious boy (Jun Saito). Goro, who was looking for hints by visiting public baths all over the country in order to do something about the troubled Obayu, wanted to work at Obayu because he wanted to work at the public bathhouse he met on his travels, so he brought him back. While being irritated by Goro's own pace, Nanae (Haruna Kawaguchi) welcomes the boy. However, the boy seemed to have some reason and stubbornly closed his heart. Meanwhile, Goro is reluctant to accept the "Obayu Renewal Plan" promoted by Nanae and others.
