Yuji studies at a private school in Tokyo. He lives alone in the dormitory. During this time, Yuji's father remarries Kana. He meets Kana once when he goes home.

Kana, not wanting Yuji to feel lonely, comes to Tokyo to meet him. They both celebrate Yuji's graduation by going out to eat. Perhaps due to being too drunk, Kana speaks her true feelings. She feels lonely because her husband is always busy with work, and that she has feelings for Yuji. And from then on, whenever the father is absent, the two are no longer mother and son, but have become lovers...
