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.

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.
