During the summer vacation, I will be taking care of my nephew, Tetsuto-kun, at my house. His husband is away from home, and his life with her son, Takashi, has become lively, but Tetsuto has been strangely close to him for a long time... Is it because of her experience of losing his mother when she was young that she has a 'mother figure' on me? You're in a bad mood, thinking that you were taken by your cousin... As I lived day by day, the distance between my family became strange, and it appeared in front of me in an unexpected way.
