Former real-life idol Karen Ishida brings extra authenticity to this idol-and-abstinence fantasy. Her role forbids dating and sex, forcing her to suppress every romantic and sexual urge—until a location shoot leaves her sharing a hotel room alone with her manager. She questions how she can convincingly sing love songs without any romantic experience, then closes the distance and makes her desire unmistakable. Her manager tells himself that satisfying her is part of preventing a scandal, but years of pent-up lust turn Karen into an insatiable force. With a tight dancer's body and endless stamina, she takes control and pushes him beyond his limits.
