The male lead is a low-level worker who is publicly slandered in front of the whole company by his busty female boss, who accuses him of peeking under her skirt. But on his way home, he happens to witness a car accident—and the driver turns out to be none other than the busty female boss. The male lead immediately seizes the leverage and threatens her, insisting on a passionate car encounter right there in the vehicle.
