My Idol Became My Brother, and Then...

Synopsis

Mukai, a young comedian, has a secret she can't tell anyone. Her senior at the agency, Nishijima, whom she calls "Nii-san," is actually the "oshi" she was once obsessed with. Keeping her past as a fan hidden, she maintains a professional distance, even though her idol is right there. One night, while drinking at their colleague Takeuchi's place, Nishijima passes out. Takeuchi, who has a friends-with-benefits relationship with Mukai, starts demanding her body right next to the sleeping Nishijima. "He won't wake up," he whispers, starting a night of forbidden passion. Despite the fear of being caught, the humiliation and pleasure of being held by another man while her idol sleeps nearby drive Mukai wild. But what if he heard her moans? Later, Nishijima drops his kind "big brother" act and confronts Mukai with raw jealousy and possessiveness. "I didn't know you could make sounds like that," he says, and their relationship spirals out of control. Forced into a hotel, Mukai learns a shocking truth: Nishijima had noticed her in the audience long ago. Their twisted mutual unrequited love, starting from "fan and performer," finally ignites.
