Meanwhile, Young Guk is a single father of three kids after losing his wife two years ago. He asks a friend to help him find a live-in tutor.

Dan Dan gets hired to work as the live-in tutor at Young Guks house, thanks to the help of Sa Ra. However, she gets into trouble on her first night on the job. Meanwhile, Sa Ra gets invited to a fancy restaurant by Young Guk and begins to get her hopes up. As Dan Dan tries to get used to living and working in Young Guks household, she runs into an unexpected familiar face.

Young Guks strict nature with his kids makes his relationship with Se Jong worse than ever. Young Guk enlists Dan Dans help to resolve the matter. Although they bicker about how to handle the kids, Dan Dans advice makes the kids grow brighter by the day. Meanwhile, a mysterious man appears before Sa Ra, which makes Ki Ja suspicious about her daughters past.

Young Guks family treats Soo Chul as if he were a parasite and a fraud, and they kick him out. As Dan Dan watches her dad endure such humiliation, she decides she must leave her job as well. The children see how sad Dan Dan is, and they come up with a plan to cheer her up. Meanwhile, Anna begins looking for a way to get back in touch with her daughter.

Dan Dan is upset that she has to lie about going to see her dad in the hospital and ends up blurting out the truth to Young Guk.

Young Guk regains his memories, throwing Sa Ra and Dae Ran into a frenzy. Dae Ran begs Sa Ra not to tell Young Guk about her involvement in their scheme, but Sa Ra declares she will not give up on marrying Young Guk. Meanwhile, Se Chan and Se Jong decide that they would rather have Dan Dan as their new mom than Sa Ra. They start to play Cupid between Young Guk and Dan Dan.

If she finds out about Young Guk and Dan Dan, the situation will only get worse.

Still, Young Guk spends night after night drinking, and Se Jongs separation anxiety gets worse. Jae Ni decides to take Se Jong to Dan Dans house. When Sa Ra finds out, they get into a fight.

Young Guk finally regains all of his memories but doesnt want Dan Dan to get mixed up in his complicated life anymore.
