San Ok, who runs a side dish store, is having a headache because of the landlord who wants to raise the rent. Even more, San Ok finds out that Dong Chul, her husband, invested all his money in a shell corporation and lost it all. Jin Ae is sick of San Ok as San Ok only favors Hyeong Kyu, the eldest son, so she wants to move out of the house.

As Hyeong Kyu left the law firm he worked for, he needs money to open his own office, so he asks San Ok, his mother, for some money. So San Ok decides to give up on her side dish store. Without knowing it, Jin Ae thinks about giving up on the rented house she barely managed to get for San Ok's store. The pipelines of Jin Ae's company go out of order all of a sudden, and Hoon Jae tries to help Ji Ae.

Jin Ae gives up on moving out of her parents' house to secure San Ok's side dish store. Although Jin Ae manages to fix the company's pipelines with Hoon Jae's help, they burst once again while the Chinese buyer is visiting the company. And Yeong Seon gets doused with water, and Jin Ae does not spare herself to save her.

As Dong Chul hit Hyeong Kyu, the household atmosphere dimmed. But Jin Ae is deeply disappointed in San Ok because San Ok asks her to give the deposit money to Hyeong Kyu so that he can open his own office. Meanwhile, worried about Jin Ae, Hoon Jae visits the factory, where he sees Yeong Seon there and hides in a women staff's locker room.

Hyeong Kyu works as a chauffeur for Jun Young and bumps into Ji Yeon, his first love. Because Hoon Jae had to go to the police station, Yeong Seon is upset, so she tells him to move out of her house right away. In the meantime, Jin Ae takes charge of the presentation of the planning team and stays late at night in the headquarters.

For a mysterious reason, the presentation is canceled on the very day, and Jin Ae is wrongfully accused as an industrial spy. The inspection team members barge into Jin Ae's room for investigation, and San Ok desperately drives them away. Meanwhile, Hoon Jae and Chul Woong have to compete once again in another project, and Joon Jae makes a bold offer this time. Hyung Soon has to quit his part-time job because of Chae Ri.
