I became a housekeeper at a home where a father and his son live together. According to the father, the mother passed away six months ago, and since then, the son, Keisuke, has stopped attending school and become a recluse. The father is determined to cheer Keisuke up but struggles with how to do it. It turns out that Keisuke has always been deeply fond of his mother's body since childhood. The story's appeal lies in understanding his feelings and gradually helping him open up emotionally.
