부부의 세계
She was living her dreams but a betrayal turned her life into a nightmare.
Ji Sun Woo is an associate director of a family clinic with a perfect life—a great career, married to a handsome, young-looking man, mother to an adoring son, and surrounded by seemingly caring friends. She couldn't be more content. Lee Tae Oh, her husband, is an aspiring movie director. However, when his temptation leads him to betray Sun Woo along with the people around her, she gets driven to revenge. The perilous twists-and-turns of a married couple's life unfolds.
Ji Seon-u's marital bliss shatters when she spots an unfamiliar strand of hair on Lee Tae-o's scarf. Suspicious, she tails him after work one day.
After making a discovery that shakes her to the core, Seon-u is thrown into a dilemma. Yeo Da-gyeong's visit to her hospital worsens matters.
A piece of unexpected news sends Tae-o running to Da-gyeong. Taking advice from a divorce lawyer, Seon-u begins gathering important evidence.
Min Hyeon-seo deals with the return of her boyfriend, who wants to cash in on her efforts. Son Je-hyeok puts forth a risky proposition to Seon-u.
While Tae-o tries to save his affair, Seon-u learns more of his secrets. They head to Da-gyeong's parents' home, where an uneasy dinner ensues.
Seon-u and Tae-o's fight turns nasty as they battle over divorce papers and for custody of Lee Jun-yeong, who struggles to process their separation.
Tae-o and Da-gyeong come back to town and throw an extravagant housewarming party. While everyone gossips about the couple, Seon-u grows anxious.
Seon-u is spooked by a series of strange incidents at home. In addition, she finds out that Jun-yeong has been hiding something from her.
Da-kyeong becomes wary of Tae-o's behavior. Before an important meeting with Yeo Byeong-gyu, Seon-u receives a panic-inciting package.
A series of incriminating photos threatens Ko Ye-rim's marriage. Reeling from a betrayal, Seon-u seeks retaliation by paying Park In-gyu a visit.
After Tae-o comes home in a questionable state, Da-gyeong snoops through his clothes. Hyeon-seo is convinced she knows the culprit's identity.
When Tae-o is taken by police for questioning, Seon-u does what she thinks is right for her family. Da-gyeong urges Jun-yeong to make a choice.
Seon-u is in the midst of considering job openings outside the city when she gets word that Jun-yeong has been involved in a fight at school.
With both Jun-yeong and her job gone, Seon-u finds herself completely alone. When she goes missing, Kim Yun-gi and Tae-o rush to find her.
Nearing the end of her rope, Da-gyeong demands the truth from Tae-o. Soon after, Seon-u shows her the upsetting reality of Tae-o's patterns.
Seon-u gradually returns to her normal life. One day, she comes home to find that Jun-yeong has disappeared — and all that's left is a note from Tae-o.
