Park Cho Sung spends her days in the office with a body that’s “too full,” a soft-spoken voice, and thick glasses that constantly fog up from embarrassment. All she wants is to work quietly—while hiding a medical condition that requires regular sexual stimulation. But one absurd incident in the office restroom leads to a literal—and physical—collision with the CEO, Lee Hwui Soe. Lee Hwui Soe is no ordinary man. A young CEO known for his cynicism, perfectionism, and iron-clad professionalism—he’s never touched a subordinate. Until Park Cho Sung falls on top of him—drenched in a thin, wet skirt, and not wearing any underwear. What was supposed to be a brief, accidental touch turns into obsession. What started as a work contract shifts into… a contract of the body. In three days, they must choose: resist temptation—or let the professional boundaries collapse entirely. Meanwhile, Park Cho Sung’s past hides a wound that could destroy Lee Hwui Soe’s reputation… and his future.
