Hyun-jung, who moved to a local mansion, was delighted with unexpected luck. She hated the noise between the floors so she wanted a quiet place with soundproofing. Since the tenants were mostly working couples, the mansion is quiet like a haunted city.

Newly-moved Yoo-jeong had a housewarming party. So-hyeon and Min-soo gather their friends at the housewarming party and meet for the first time. Yoo-jeong falls asleep alone, and Min-soo secretly kisses Yoo-jeong. So-hyeon, who finds out, threatens Min-soo and plays with him. Min-soo had no choice but to accept So-hyeon's terms. Yoo-jeong misunderstands them. But in the process, Yoo-jeong herself finds herself interested in Min-soo. Recognizing that, So-hyeon gives up the room he originally intended to live in to Min-soo and leaves.

When they were young, Min-joo and Seo-yeon cared for each other and were closer than brothers and sisters. However, she accidentally learns about Seo-yeon's tutor, Woo-hyeon, and because of this man, their 10-year friendship starts to become shaky. Meanwhile, Jeong-soo is hurt in seeing Min-joo like that, and so he distanced himself from Min-joo. Because of Min-joo and Seo-yeon's misunderstanding, Jeong-soo who couldn't care much might just leave so Min-joo tries to break up with the help of Seo-yeon. While in the process of breaking up, Min-joo and Seo-yeon went back to their close relationship. The love of women who have been separated because of man, and the two men's friendship is comically drawn.
