"Do what you want, I'm going back to Tokyo!" Haruko storms out, leaving Aki behind. Daikichi goes after her and stops her from boarding a bus bound for Tokyo. He tells her to ride the local train, KitaTetsu* and while she waits for her ride, they hang out at a cafe (run by her mother who is out diving at the moment) at the train station. Here, Haruko complains about how she does not understand her daughter Aki. "She's quiet, plain and gloomy, just like her father." She did not notice the time and misses the last train so she is forced to stay overnight. By then, Natsu arrives at the cafe and tells her to go to some business hotel. "You don't have to tell me!" Haruko again, irked, storms out, taking her luggage with her. But Daikichi manages to bring her back to the cafe which at night transforms into a snack bar. The next day is Umihiraki** which is also the season of the Ama. Aki is at the beach along with many tourists to kick off the event. Meanwhile, Haruko is hanging out at the pachinko parlor where she attracts unwanted stares from people who knew her from before. Feeling uncomfortable, she offers her winning pachinko machine to Adachi Hiroshi, the young man sitting next to her before leaving. She goes to the seashore where she sees Aki and Natsu on a boat. She also watches in horror as Natsu pushes Aki down into the water...
