Lamune

Synopsis

A flashback shows that Hiromi and Kenji met when they were kids. Hiromi was immediately smitten by Kenji who traded her a bottle of lamune for her blue hairpin. Before giving her the bottle, Kenji took a drink from it: an indirect kiss in the making. Ever since then Hiromi has cherished the bottle. Sad that she is moving away, she is pleasantly surprised by Kenji and the others who arrive to help pack and spend what little time remains with her. As the finish packing, Hiromi's precious bottle is accidentally broken. Later, Kenji and Nanami see her off to the train and Kenji gives her another bottle of lamune. Amazed that he remembered, she gives them some last minute advice before she leaves.
