Mitsuko gets in contact with Oyamada in order to have one wish granted: before entering a nursing home, she wishes to spend a night as she was 35 years prior. During that night, Mitsuko mistakes Yume for Kana, her daughter who used to be a violinist and who died in an accident in Vienna. Mitsuko herself used to play piano. In the anime, Mitsuko instead asks Oyamada and Yume to turn her house back to the way it was 50 years ago.
