Housewife Kyoko Maki, facing financial difficulties and unable to pay rent, turns to her landlord for help—offering her body as collateral. What began as mere blowjobs quickly escalates, as she is gradually treated like a sex toy, used and abused at his whim. The landlord, fully exploiting his power, taunts her with, "Feel free to leave anytime if you want? LOL," trapping her in complete submission. Though she initially sacrificed herself for her husband's sake, Kyoko soon awakens to sexual pleasure, losing herself to desire and surrendering her heart entirely.
