Kimura has a first love person. It's the light of my best friend's mother. It's only recently that I've begun to be aware of the light of being more like an older sister than a mother. After becoming aware of his love, Kimura goes to his best friend's house with all his heart to meet the light. Even though I have a favorite partner in front of me, I can't do anything, but the painful days continue ... Maybe Kimura's efforts have paid off, and I have to stay for some reason.
