Year 10 of the Taishō era. The life of Tamahiko Shima, who lives in exile in the country after having lost everything, changes completely with the arrival of the young and innocent Yuzuki.

Spring of 1922 arrives and Tamahiko continues to get used to Yuzuki. Tamahiko receives a letter from her father, Tamayoshi, announcing that two of Tamahiko's siblings have been given marriage proposals and that, as a result, he has made a shocking decision that affects Tamahiko.

Tamahiko's sister, Tamako, arrives to settle in the mansion with her brother and Yuzuki, but she still shows a cold demeanor towards both of them. This causes Tamahiko's mood to sink again, until Yuzuki takes him for a walk to appreciate the beauty of the natural landscape around the house.

Tamako move to her uncle's house in Kobe to begin her studies in medicine. Later that day, Tamahiko and Yuzuki go shopping at the village market where they draw the attention of young Ryo Atsumi. At night, Yuzuki gives Tamahiko a birthday present.

Tamahiko tracks Ryo down to her home, only to discover that she is the oldest of three younger siblings and her theft is due to the fact that her father is an abusive alcoholic. The next day, Tamahiko returns to Ryo's home to try to retrieve the bookmark she stole from him and Ryo agrees to return it if Tamahiko helps her younger siblings with their school homework.

An injured Yuzuki reflects on some moments in her life since she met Tamahiko and laments her inability to express her feelings. She wishes she could survive and meet Tamahiko again.
