When they were young, Kenji traded Hiromi the lamune bottle that he had just bought for her blue fish hairpin. He took a drink of it before giving it to her, and so the two shared an indirect kiss. To this day, Hiromi has kept and treasured this bottle. But now it’s time to move away, and Kenji and company show up to help out. While carrying a table, Hatano accidentally bumps into Hiromi, causing the special lamune bottle that she had in her arms to go flying out the window and break on the ground below. Hatano apologizes, but Hiromi claims that it wasn’t anything important. That night, the group has a farewell party at the Konoe family restaurant. Afterwards, Suzuka takes Hiromi to her room, gives her a going away present, and asks for Hiromi to write. Kenji calls Suzuka downstairs, so Hiromi uses the opportunity to go into Kenji’s room. She looks around and spots Nanami through the window in the house next door. Hiromi feels a bit sad, but says to herself that it doesn’t matter since she’s moving away.
The next day, Nanami wakes up to motorcycle noises next door – it appears that Kenji has finally fixed the bike. He and Nanami go to the train station and arrive just in time to catch Hiromi before she boards the train. Kenji gives her another bottle of lamune, and the three say their goodbyes. Sakura tells Kenji and Nanami that they are the best couple, but that they shouldn’t keep feeling that it’ll be always ok like this. As the train pulls away, Nanami holds Kenji’s hand and then hugs his arm.
Surprisingly, the second Hiromi episode brings Kenji and Nanami closer together. There are several tie-ins to last episode, including showing where the blue fish hairpin that Kenji showed Nanami came from and showing the extended version of Hiromi’s confession. And then there’s the warning she gave them at the end, basically urging them to confess to each other. After that, we see Nanami and Kenji get a bit physically closer. So with a few episodes left and the motorcycle now fixed, the series is getting to the point where their relationship will probably climax with a confession. The preview seems to show, among other things, Nanami and Kenji in one room with only one bed.
