Jungo is a gay high school student living in Ota City, in the Gunma Prefecture of Japan. He has a boyfriend, Yusuke, who is hesitant about entering into a formal partnership with him because of his race and poverty: Jungo’s mother, Reina, is from the Philippines and works at a Filipina hostess bar. Despite Jungo’s repeated questions about his father, Reina has never told him anything about the man. One day, Reina brings her new boyfriend home, and tells Jungo she wants to remarry. Jungo is enraged by the idea of living with this stranger, and sets out on a quest to find his biological father.
