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.

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 finds out that Tamahiko wants to go back to school, so she puts him in touch with his uncle Tamasuke, who decides to help him. Meanwhile, Yuzuki learns about her favorite singer Kotori Shiratori coming to town for a performance, so Tamahiko decides to take a break from his studies for the remedial exam to go with Yuzuki and the local kids.

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.
