Yu and Yuko originally met at an orphanage twenty years prior. Yu had lost his younger sister in a fire, and continued to be troubled by it for years. Once in high school, Yuko confesses that Yu was her first love, and she still loves him. In the present, Mizuki comes over to Kuze's and he helps her with some laundry. Kuze later collapses in Mizuki's presence, and she makes sure that he is comfortable while he sleeps it off. That night, Mizuki comes over again because she cannot sleep and tells him how touched she was after listening to the CD of Kuze's violin music he gave her. Before she leaves, she tells him that she has fallen in love with him.

In the past, Yu and Yuko go out together to buy new boots for Yuko, and while Yu does not consider this a date, Yuko and her elder brother do; after Nagi catches wind of this, she confronts Yu about it. In the present, Nagi helps Hiro draw his manga in order to beat the deadline, and Miyako makes dinner for him. Mizuki gets a cold and Kuze comes to pay her a visit. After she gets better, the two go out to the surrounding countryside and spend the rest of the day together with Kuze resting his head on Mizuki's lap. Kuze tells her that before he dies he wants to end all relationships, and even though he too has come to love Mizuki, he tells her to never appear before him again.

In the past, Yuko continues to go through being bullied, and this time she fights back, but gets injured in the process. Yu starts worrying about her more, and is angered that her older brother does nothing to help Yuko. In the present, Kei has a talk with Kyosuke about Chihiro, and he suggests that she go and visit it her. When they meet again for the first time in five years, they make amends with the past, and reflect on their futures with those they love. Mizuki wants to be stronger like Chihiro and Kei, but does not know how. When Mizuki expresses this doubt to Nagi, Nagi reveals that she is in fact going out with Kuze.
