Seira, an office lady, is approached by a scout during her lunch break, and this encounter leads her to transition into a modeling career for a fashion magazine. However, her initially successful modeling work gradually sees fewer contracts, and her income dries up. To support her living expenses, Seira repeatedly borrows money from her agency, which slowly accumulates into overwhelming debt. One day, she is summoned to the agency office and pressured by the president to repay the debt. The loan agreement she casually signed turns out to include exorbitant interest rates, leaving Seira shocked. The president then proposes one way for her to settle the debt: participating in a "Public Orgasm Show" attended by wealthy men from various industries. For Seira, there is no other choice.
