Seung-hye moves to a new house that she has been looking forward to so much with her junior, Na-yeong, but is swindled by a double contract and moves in with a strange man, Soo-cheol, and his senior Hyeon-joon. Armed with powerful male hatred, Seung-hye distanced herself from the men even by dividing the house in half, but her junior, Na-yeong, falls into the hands of Hyeon-joon, a wolf dressed in sheep's clothing. Seung-hye hates men's genitals because male hatred is deeply ingrained in her brain. To this Seung-hye, she suddenly witnessed Soo-cheol's genitals. She tries to forget it, but the penis stuck in her mind and she can't unsee. She concludes that Soo-cheol "fooled her into liking sex" and treats Soo-cheol as a rapist.
