Synopsis
It revolves around the story of four women in their 30s and their complex relationships - each on her own path to self-discovery as they brave the turbulent journey together.

The series starts with Se-Yeon (Han Ga-In), Eun-Soo (Shin Hyun-Been), Jung-Won (Choi Hee-Seo) and Hwa-Young (Goo Jae-Yee) who have a dead man's body in front of them. Se-Yeon has three close friends: Eun-Soo, Jung-Won and Hwa-Young.

2 months prior, Se-Yeon runs a cafe. She has a daughter, whom she loves very much. Her husband died 2 years earlier, but his body was never found. She then receives a phone call without a caller ID number. The caller plays her husband's favorite song, unnerving her. Song-Hoon (Lee Hee-Joon), a divorced father whose daughter attends the same kindergarten as Se-Yeon's daughter, tries to initiate a romantic relationship with her. Se-Yeon's friends encourage her to pursue this relationship.

Eun-Soo works as a psychiatrist. One day, her patient Sun-Ho (Jung Ga-Ram) tells her that he is looking for his dead father's mistress. He believes that the mistress killed his father. Sun-Ho vows to kill this mistress, hinting that he is aware of Eun-Soo's relationship with his late father. Eun-Soo does not tell her client that she is the one who had the secret affair with his father, nor that she was the one who found his dead body. Eun-Soo also has another secret.

Jung-Won is a high school teacher. She is married to a famous chef Dong-Seok (Park Byung-Eun). He seems like the perfect husband. Dong-Seok wants to have a child badly, but Jung-Won doesn't know the real reason why her husband wants a child. Dong-Seok continuously tracks Jung-Won's ovulation. Meanwhile, Min-Gyu (Ji Il-Joo) is a temporary teacher at the same high school where Jung-Won teaches. Min-Gyu ultimately blackmails her after seeing her leave a motel, knowing it will cause the vice principal at her school to fire her, however, Min-Gyu has an ulterior motive.

Hwa-Young works as an office administrator at a law firm. She enjoys her single life and she doesn't want to be tied down with one man. One day, a female client comes and requests that someone secretly follow her husband Tae-O (Kim Min-Soo). Hwa-Young takes this task but realizes that the man is Hwa-Young's ex-boyfriend.
