In the recent pandemic, the underground idol industry has been filled with a tense and fearful atmosphere. Even Nanami, who is usually pampered by everyone, has been spending her days in frustration and boredom, unable to perform live or attend events. One day, upon hearing rumors that her sister has gotten a boyfriend, she decides, "I can't allow my sister to be happy," and plans to steal her sister's boyfriend as a way to vent her frustrations. The idol, turning her daily stress into sexual desire, surpasses her limits and transforms into a dangerous, lustful psychopath. Her twisted expressions of love escalate into extreme M-boy training.#chinP
