As Valentine's Day approaches, Tamako suggests the shopping district should hold a Valentine campaign. However, Tamako's father, Mamedai, is against the campaign, believing it to be too modernised. As Tamako and Mochizō start shooting a commercial for the shopping district, Tamako's friend, Midori Tokiwa, feels conflicted by feelings she starts having around Tamako. At the screening of the commercial, Dela manages to stand in for the projector by projecting the image through his eyes. When the commercial finishes, Dela shows another video, this time a video message from his home country. As Valentine's Day arrives, Midori comes to terms a little with her feelings.

As the Tamaya shop decides to put on a mochi pounding event for October 10, Mochi Day, Anko asks Tamako to set some daifuku aside for Yuzuki, the boy she has a crush on, but can't bring herself to face him in person. Asked by Tamako to help, Mochizō learns that Anko is depressed because Yuzuki is transferring to another school on Mochi Day. As Mochi Day arrives, Tamako gives Anko the encouragement to see Yuzuki off before he leaves. Receiving some fresh mochi Tamako gave Anko, Yuzuki tells her that they'll see each other again when his family next comes to Tamaya for some mochi. Meanwhile, Tamako comes across Mamedai playing a familiar song from her childhood. The record store owner, Kunio Yaobi, tells Tamako and the others that the song was written by Mamedai for her late mother, Hinako.
