Titre original : I Caught a Sea Urchin
Instead of being angry, Haruko is happy to see her old room again. "These bring back so many memories!" She laughs while looking around. She finds an exchange diary she and Sugawara had in high school, and a video game cartridge she borrowed from Anbe. She also shows Aki her "secret base" which is the beacon at the seashore. Aki reads the stuff her mom wrote on the ground when the latter was a teenager. "You're like Yui (who wants to go to Tokyo)." Later they return to their futons, and Haruko tells Aki a diving tip she learned from Natsu. "When you want to dive deeply and longer, don't think too much because your brain uses up too much oxygen." The next day, Aki reiterates her desire to join the "Honki Dori" event. The Ama-sans tell her only one person per household can join to prevent over-fishing. "If you go, then Natsu can't go." However, Natsu says Aki can take her place. The Ama-sans wonder if it was a good decision, considering Aki can't catch any uni yet. At the train station, Aki chats with Hiroshi. He apologizes to her for causing all the fuss by uploading her video. He also says the more popular she gets, it seems "the more you get farther away (from him)." Then, since he couldn't contain his feelings any longer, he startles Aki by confessing to her. "I'm in love with you!" (While assistant trainmaster Yoshida Masayoshi eavesdrops). But Aki remembers the diving tip her mom had told her. She covers her ears and says, "No no! I mustn't think of anything! Tomorrow's the Honki Dori! How could you do this to me?!" She runs off leaving Hiroshi behind. That night, Aki lies in bed, counting uni (instead of sheep). She tries to fall asleep but she just could not erase Hiroshi's confession off her mind.
