The Suspicious Housekeeper

Sang Chul hires Bok Nyu as a housekeeper when taking care of the house becomes difficult after his wife's death. Director Hong Bun Nam from the agency warns Sang Chul to be careful because Bok Nyu does anything she is asked. Meanwhile, Sang Chul's sister-in-law, Na Young, promises Hye Gyeol, her niece, to let her meet her mother when Hye Gyeol says she wants to meet her dead mother as her birthday gift.

Han Gyeol finds out that her mother, Sun Young, committed suicide because her father, Sang Chul, was having an affair. After Han Gyeol learns her father has been cheating, she visits his father's mistress, Song Hwa, and shows her mother's suicide note to her. Meanwhile, Sang Chul is uncomfortable with Bok Nyu, so he goes to the employment agency to request to replace Bok Nyu with another housekeeper.

Han Gyeol shows her mother's suicide note to her younger siblings and tells them that she cannot live with their father, Sang Chul, and leaves with them. After leaving her house, Han Gyeol and her siblings stay at their grandfather's house. Meanwhile, Hye Gyeol visits Bok Nyu and asks Bok Nyu to kidnap her to bring her family back together.

The four siblings ask their dad, Sang Chul, to leave the house. And they want Bok Nyu to stay with them and ask Sang Chul to allow her to work for them again. Meanwhile, Sang Chul explains to Bok Nyu that it was a misunderstanding when she caught him with Song Hwa. Geum Chi, Sang Chul's father-in-law, accidentally sees Sang Chul and Bok Nyu and becomes suspicious of their relationship.

Han Gyeol goes to meet her father, Sang Chul, to discuss about Bok Nyu. However, Han Gyeol is furious when she sees an engagement ring in Sang Chul's room. Meanwhile, Du Gyeol accidentally watches a pornographic video while searching for Park Bok Nyu on the Internet. And he is caught by Bok Nyu while watching it.

Du Gyeol and Se Gyeol ask Han Gyeol to let their father come back home, but she wants to get revenge on Sang Chul. Bok Nyu tells Han Gyeol that what parents are scared of the most is their child getting ruined. Meanwhile, rumors spread throughout the school that Han Gyeol is doing teenage prostitution and she runs away from home.
