The atmosphere is gloomy at the Fishing Co-op as Aki's return to Tokyo draws near. A touching moment passes between Natsu and her granddaughter when she feeds Aki with sea urchin for the last time. "Don't you forget the taste." Hiroshi also bids Aki farewell, gifting her with free curry tickets from a shop in Tokyo. That night, the Ama-sans and the men discuss and lament about the mother and daughter's impending departure. The women insist that Daikichi propose to Haruko so she won't have to leave. Natsu chooses not to do anything about the situation, quoting her favorite line: "Those who leave will not be pursued.* " Meanwhile, Haruko wants to ask Aki if she really wants to leave. But Aki, bottling up her true feelings, says she's fine about returning to Tokyo. Natsu comes home, and goes straight to bed early, ignoring the fact about their leaving. "Gotta get up early. Better go to sleep." Haruko remembers that those were also the words she said the last time when Haruko left home 24 years ago. "If there's something we have to talk about, you always turn a blind eye and pretend to sleep!" The next day, the Ama-sans gather at the house to say goodbye, except for Natsu who went to the beach to gather seaweeds. Daikichi is supposed to propose but backs out. At the station, Aki hesitates to ride the train home. Haruko asks her what she really wants to do but Aki still says she's okay with it. Just in time, Haruko steps off the departing train and pulls Aki with her. The train leaves without them. They go back to Natsu's home, much to the delight of the grandmother.
