His mother has never told him about his father, and the only connection he has to his father is the monthly child support payments. Jungo is homosexual and has a boyfriend, Yusuke (18). Even though Yusuke wanted to form a partnership with him, he was reluctant to do so because of his background. One day, his mother, Reina (41), brings her boyfriend home, saying she wants to remarry with him. Jungo doesn't want to live with a stranger, so he decides to find his real father.
