This role-play is performed by adults. During the summer vacation, I will be keeping my nephew Tetsuto at my house. My husband is away on his own and my life with my son Takashi has become lively, but Tetsuto has always been strangely close to me... Is it because of my experience of losing my mother when I was young that I have a “motherly figure” attached to me? You are in a bad mood, thinking that your cousin has taken me away... As I lived day by day, the distance between my family and friends became strange, and this feeling of discomfort appeared in front of me in an unexpected way.
