Jin Goo wants to break off his engagement with Se Young, but after she collapses and finds out she's pregnant, she decides to play that card to rope him back in, claiming it's his and not Ji Seok'a child.

A strange caller starts the romour about Yeo Jin's daighter being dead, which create an overall commotion. Se Young trips Ha Na in cafeteria to vent her frustration, but that backfires when Ha Na's sister hits her with a tray. Se Young typically faints and pretends to be the victim, until someone suggests to check the CCTV camera to find out if she tripped Ha Na on purpose.

Ha Na moved to Yeo Jin's house and is getting used to living there. Se Young is doing her best to try to adapt to her new role after having a meltdown during Ha Na's appearance.

Yeo Jin plans to meet her husband, but the meeting is thwarted by Ji Seok. Ha Na and Eun Chong move in with Chairwoman Yeo Jin.

Ji Seok is adamant about cutting ties with Ha Na, and tells his siblings to do the same or to cut it with him instead.

Ji Seok has hard time accepting Ha Na is chairwoman's missing daughter, and if there's no avoiding that he tells Ha Na to sever all ties to him as his siblings.

Everybody is curious about who Yu Jin is. Se Young is having a hard time accepting Yu Jin will return in case she remembers her past. Chairwoman Yeo Jin visits Ha Na's family and tells everyone she is her lost daughter. Ji Seok overhears it from the entrance.

Yeo Jin and Ha Na meet with DNA confirmation that Ha Na is Yeo Jin's missing daughter. Se Young and her mom try to find out with whom Yeo Jin is meeting, but their plans are thwarted by Ji Seok.

Se Young's mom stirs trouble at her company by hitting Ha Na and Ji Seok reports the assault. Yeo Jin still considers making Ha Na her missing daughter so she can live together with her supposed grandchild.

Ha Na finally shows some backbone and turns the situation at her workplace to her advantage. Yeo Jin finds out her daughter died (which we know is false), but that she has a grandson (which we also know is false).
