When Eun-beom is on the verge of losing the custody lawsuit because of Ha-ra's hidden card, he reveals that his affair with Seo-hee was all fake. What is the truth behind their divorce?

Eun-beom accidentally finds out a huge secret about Ha-ra's father. As a result, he continuously hovers around Ha-ra and can't decide whether to tell her or not. Meanwhile, Bi-chwi and Si-wook deal with a divorce case caused by personality differences, which puts their secret relationship in danger of being exposed.

Eventually, Ha-ra finds out about her father's secret, which greatly shocks her. Because of this, Eun-beom takes a case on her behalf, and by doing this, Ha-ra suddenly feels some subtle feelings towards him.

Realizing that she still in love with Eun-beom, Ha-ra sets up a crazy plan. She starts telling Eun-beom that she loves him and they should get back together and if she gets rejected ten times, she'll get over him completely. Meanwhile, Eun-beom reflects on her complicated relationship with Ha-ra while defending the murder case that deals with complicated love and hate.

Ha-ra and Eun-beom finally got back together. However, when Ha-ra takes on the divorce suit of her cousin, who lived as a DINK, a serious question arises between them: whether or not to have a child.

Ha-ra learns the whole story of Eun-beom's younger sister's death and finally understands Eun-beom's fear of raising a child. On top of that, seeing Han-gil endure all kinds of humiliation due to his ex-wife's dispute over animal custody makes Ha-ra think about things.

Ha-ra and Eun-beom have repeatedly agonized about having a child but eventually broke up due to a minor misunderstanding. Ha-ra decided to take on the divorce proceedings of clients who broke up and reunited several times, just like them.

Eun-beom is tormented by the breakup and eventually decides to leave the office again. Ha-ra tries to understand Eun-beom and helps him when his mother files a lawsuit due to the worsening conflict between them.
