During the summer vacation, I decided to take care of my nephew Tetsuto at my house. My husband was assigned to work alone, and my life living with my son Takashi became lively, but Mr. Tetsuto has been strangely close to me for a long time. Is the experience of losing my mother at a young age superimposing on me as a 'mother'? You're noble, and you're in a bad mood because you think you've taken me as your cousin. I felt a sense of discomfort as the distance between my family became strange as I lived day by day, and Sorae appeared in front of me in an unexpected way.
