As soon as she sees Yui, Aki gets up and locks herself inside Natsu's workshop. Yui knocks on the door. "Aki-chan, I'm sorry! We're not really going steady! It was just a misunderstanding with Taneichi-senpai! But I didn't want it to be awkward between us..." Haruko says to Yui that she does not have to apologize that Taneichi chose her instead of Aki. "It wasn't your fault. It's okay... somehow there's no one who doesn't go through a broken heart." Haruko invites Yui inside for some yakisoba. Yui explains about what happened. "I'm a person who doesn't need such a boyfriend. Got so annoyed seeing Aki-chan so flighty. Maybe I felt a bit jealous... I said, 'Why not me? Why Aki-chan?'... He does look cool. And... He said he's going to Tokyo..." Haruko understands. "Ah! You wanted a boyfriend who lives in Tokyo... But you know, somehow, I think Aki has changed. Has become more assertive compared to before." Meanwhile, Aki is frustrated and hungry inside the workshop. Yui leaves wishing her speedy recovery. Aki goes back to school but refuses to talk or be with Yui. At the shop, Natsu has told Daikichi that Aki will not be participating in the parlor train event anymore. "JEHHH~!" Daikichi says all the tickets have been sold out and the event had cost around 10 miilion already. So he asks for an emergency meeting. This emergency meeting turns out to be an interrogation of Taneichi, asking him to go and date Aki.
