Due to her husband’s abuse, she divorces and is raising her son alone. Tired from daily life, she goes on a trip to an onsen (hot springs). The male employee there turns out to be her long-lost son. At first, the mother doesn't realize it's her son, but he eventually reveals his true identity. The son, harboring resentment towards his mother for abandoning him, says, "I can't see you as my mother anymore. Because of you, my life is in shambles. I'm still a virgin at this age... If you're going to act like a mother, then teach me about women." He threatens her. The mother, feeling inadequate, offers her body, saying, "I'm such a useless mother, I'm sorry." They engage in sex, and the son continues to pursue a relationship with his mother. A broken mother-son relationship begins to form.
