After learning that Koharu, who had been out of contact, is in the hospital, Kakeru, Narumi, and Yuko rush to see her. In the hospital’s kids’ room, Kakeru finds Koharu playing the piano for children. When he speaks to her, she responds with, “Who are you?” and rejects him. From Koharu’s mother, Haruka, they learn that Koharu’s memory has become confused due to a certain reason, leaving them in shock. Meanwhile, Koharu spends her days volunteering in the hospital's kids’ room, playing the piano for the children. One day, determined to spend more time with Koharu even if she cannot remember him, Kakeru takes action.
