Park Joo-mi made debut in entertainment as an Asiana Airlines model, then began acting in 1991, starring in television dramas such as Beautiful Seoul(1999) and Feels Good (2000). After appearing in Ladies of the Palace, Park married businessman Lee Jang-won in 2001 and temporarily retired from acting to focus on her family. After almost a decade, she made her screen comeback in the thriller Man of Vendetta (2010) and the family drama Believe in Love (2011).
This series follows the lives of three married couples, who are in their 30s, 40s, and 50s. With successful careers and families of their own, they seem to live happy lives. However, their “perfect” marriages hit a snag when each of the women was betrayed by their husbands. The youngest couple is Boo Hye-ryung (Lee Ga-ryeong) and Pan Sa-hyeon (Sung Hoon), the typical millennial couple. She is a popular host for a radio show, while he is a famous lawyer. Having been married for just three years and without any child between them, life was constantly on-the-go. Married life is mostly about career, dinner-outs, and partying largely because of Boo Hye-ryung’s domineering personality and lifestyle choices. Out of the blue, her husband shocked her with a confession that he has gotten another woman pregnant, and he wants a divorce. Sa Pi-young (Park Joo-mi) and Shin Yu-shin (Lee Tae-gon) are a couple in their 40s. Sa Pi-young is the producing director of the same radio show that Boo Hye-ryung hosts. Despite having to juggle a busy career, she is also very much involved in taking care of everything at home. Meanwhile, Shin Yu-shin is the director of a hospital’s neuropsychiatric department. He is every bit the perfect husband and father, but underneath all that, he actually holds a dark secret which he hides so well. Lee Si-eun (Jeon Soo-kyeong) and Park Hae-ryoon (Jeon No-min) are the oldest couple in the bunch. Lee Si-Eun is the main writer of the radio show. When they started out, Lee Si-eun worked doubly hard to support her husband which allowed him to work as a professor. They have been married for thirty years, and Lee Si-eun has no problem doting on her family. However, Park Hae-ryoon seemed to be in a midlife crisis. He was already unhappy with his seemingly mundane activities and to his luck, he found a piece of excitement elsewhere.
