Aki swims away leaving her arguing relatives behind. She goes to the Fishing Co-op, and stays late to chat with the people there. She enjoys listening to them talk about the personal lives of Daikichi and some of the Ama-sans. Hiroshi drops by and tells Aki he saw her jump into the sea again but did not sound the siren because she looked fine. At the Amano home, Haruko and her husband discuss about the divorce. She tries to explain why she wants to divorce him, albeit vaguely, saying that it maybe good for Aki and herself. But Masamune does not see a reason why they should since he was a man who prioritizes his family more than his job (which Haruko wished for in the first place). Anyway, Haruko says she already made up her mind and had signed the divorce papers using the Amano (her maiden name) seal. But Daikichi and Anbe tell her that she should have used her married name seal because if not, the document will be invalid. Haruko: "Oh, I didn't know that since I've never been divorced before." Later, Masamune goes to the bar with the men and tells how he met Haruko in Tokyo in 1988. She was a passenger of his and they hit it off well, dated and got married. Yayoi (Ama, 59 yo) tells him that Haruko grew up in a family whose parents were not always at home. "When you're with someone all the time, soon you won't have anything to talk about." Then, Daikichi (who is weak against alcohol) passes out, apparently unaware that Yayoi was serving him oolong tea mixed with alcohol. Back at the Amanos, Aki arrives home, looking cheerful. Haruko is supposed to tell her about the divorce but Aki (thanks to her recent helpful chat with the Ama-sans) says there is no need to say anything because she understands that Haruko is going through a lot of things. The next morning, Masamune goes to the beach again to see Aki... He watches her from a distance, noticing that Aki is happier and laughing cheerfully - a far cry from the gloomy and shy daughter that he had known in Tokyo...
