Why... The remarriage partner brought by my father is Yuko, a nurse. He is the first love who took care of Atsushi who was hospitalized. Yuko managed to endure the painful hospital life as a side dish. It is said that Yuko will marry her father and become a family from today. The person in mind is taken by the father. Atsushi, who was jealous of his father as a man, decided to cross the line with Yuko, who became a new mother.
