One morning, Asahi (Satoshi Tsumabuki) and Azusa (Yu Aoi) are arguing over the name of their child. Azusa, who is disappointed with Asahi's idea, suggests that they name their child after the image of the sun, like Asahi and his siblings. Asahi begins to think of a name that starts with “A” and evokes the image of the sun, like Asahi and Azusa. Meanwhile, Tadashi (Shuhei Nomura) is shocked to realize that the bracelet worn by Yo (Tasuku Emoto) is the same as that of Kasumi (Ai Hashimoto).
