During the summer vacation, I've agreed to take care of my nephew Tetsuto at my home. My husband is on a single assignment, and my life with my son Takashi has become livelier. However, Tetsuto has always been oddly close... Could it be that, due to my experience of losing my mother at a young age, he sees me as a 'mother figure'? Takashi, on the other hand, is unhappy, feeling overshadowed by his cousin... As days go by, there's a growing sense of unease about the strange distances within our family, and it manifested in unexpected ways before me.
