At Pinky Pop, an innovative adult toy company, the corporate culture is anything but ordinary.

When the chronically unlucky Nari draws the winning ticket, she thinks she can handle the heat. But when sharp-eyed Manager Seo catches onto her suspicious behavior, he offers a deal: he’ll keep her secret, provided she gives him a very private demonstration.
