Good Partner

It’s Yu Ri’s first day at Law Firm Daejeong, 1 of Korea’s top 3 law firms. She thought she’d be joining the corporate department, but instead, she was assigned to the divorce department. Eun Kyung, the nation’s divorce attorney, instantly knows that Yu Ri isn’t the right material for a divorce attorney. However, Yu Ri tries to win the case in her own way.

Yu Ri’s straightforward nature struggles to comprehend some of the methods Eun Kyung employs. She is particularly shocked when she sees Eun Kyung persuading her clients to prioritize economic benefits over child custody. To Eun Kyung, who possesses far more experience than a novice, Yu Ri is just a rookie in the big leagues. What astonishes Yu Ri even more is Eun Kyung's reaction after she reveals a little secret she’s discovered.

Yu Ri is surprised to hear that Eun Kyung doesn’t want to divorce Ji Sang even after finding out about his affair with Sa Ra. Yu Ri finally starts a session with a client on her own and gets her first case. However, the client decides to drop the lawsuit. Yu Ri decides to quit working for the divorce team.

Eun Kyung asks Yu Ri to represent her for her divorce case against Ji Sang. Eun Kyung sends a letter of complaint to Sa Ra, letting everyone in the office know that she was involved in an unsavoury incident. Rumours about Eun Kyung and Ji Sang’s divorce circulate, but Eun Kyung doesn’t even bat an eye.

Ji Sang secretly leaks to a reporter that Eun Kyung might have an office husband and that she had an affair before him. Yu Ri decides to hear whether Eun Kyung and Woo Jin had an affair or not. Yu Ri convinces Eun Kyung to settle, but Eun Kyung doesn’t give in. Meanwhile, Yu Ri comes up with a brilliant idea to change the public’s opinion of Eun Kyung.

The first hearing of Eun Kyung and Ji Sang’s divorce trial begins, and neither side wants to give up the custody of Jae Hui, their daughter. Jae Hui misunderstands Eun Kyung’s intention and thinks she wants to let her live with her father. Meanwhile, Yu Ri takes on a case of a couple who want to give up their custody.

As soon as Sa Ra gets promoted to chief manager, she gets dismissed from the law firm. Ji Sang tells Sa Ra that he has no intention of marrying her even if he gets divorced, which leaves her devastated. Meanwhile, Yu Ri’s stepmom comes to see Eun Kyung and threatens her to fire Yu Ri.

Sa Ra is pregnant with Ji Sang’s child. However, Ji Sang’s lawyer advises him to abandon Sa Ra to win custody of his daughter. Sa Ra secretly puts the ultrasound picture of her baby in Jae Hui’s room, and Jae Hui eventually sees it. Meanwhile, Jae Hui finally meets the family investigator.
