The Penthouse

Dan Tae and the residents of Hera Palace prepare a proposal for Seo Jin. However, police officers barge in and arrest Dan Tae as the murderer of Su Ryeon. While Yoon Hee turns herself in, she runs into Dan Tae and Seo Jin at the police station. Now that Dan Tae is a new suspect, other residents also start to believe that he killed his own wife.

When Yoon Chul introduces Yoon Hee as his wife, everyone gets shocked especially Eun Byeol. Seo Jin can’t stop thinking about Yoon Chul and it leads Seo Jin and Dan Tae to have a huge fight. Meanwhile, the doctor warns Seo Jin not to sing for awhile, but she can’t give up on her concert as it can damage her reputation.

Seo Jin is shocked to find out that Yoon Hee sang for her instead of Young Ran. The more Yoon Hee tries to bring Seo Jin down, Seo Jin feels insecure. She gets mad at Secretary Do and tells him to find a way to stop her. Meanwhile, Dan Tae also notices that Seo Jin is hiding something from him and questions Secretary Do to discover her secret.

Out of the blue, Yoon Chul visits Seo Jin at the hotel where she’s supposed to meet Dan Tae. As Dan Tae arrives, Seo Jin quickly hides Yoon Chul in the closet. Meanwhile, Ro Na comes back to Cheong A Arts High School and Ma Ri gets furious after finding out that her daughter, Jenny is being bullied by Seok Kyung and her friends.

Seok Kyung threatens Seo Jin with a secret she claims to know about her for the grand prize given at the Cheong A Art Festival. Ma Ri flips out on the parents who bullied Jenny and warns them she won't back away until everyone involved gets punished. Meanwhile, Seo Jin finds her mother and sister in her office with a non-disclosure agreement and tells her to step down from being the director.

A janitor who found Ro Na on the staircase runs into the auditorium, screaming when Seo Jin announces the grand prize winner of the Cheong A Art Festival. Ro Na goes unconscious and Yoon Hee suspects Eun Byeol. When Seo Jin realizes that the culprit was Eun Byeol, she goes back to school to find the trophy in Eun Byeol's locker and runs into Yoon Hee and Ma Ri.

Eun Byeol is going mad day by day, and Seo Jin calls Yoon Chul for help. When Yoon Hee finds out that Yoon Chul is also involved in Ro Na’s death, she runs to Cheong A Medical Center to find him. Dan Tae uses Seo Jin’s weakness to gain more power and wealth, and Yoon Hee uses her biggest secret to bring her down in front of the public.

Yoon Hee meets Ae Gyo for the first time, and she is surprised as she looks just like Su Ryeon who is supposed to be dead. Seok Hoon tries to figure out what Eun Byeol has done to Ro Na, but Eun Byeol can’t remember anything that happened during the Cheong A Art Festival. Meanwhile, Yoon Chul is too guilty to stay by Yoon Hee’s side anymore, and he decides to leave her.

Yoon Hee and Logan try to persuade Ae Gyo to stay away from Dan Tae, and they leak information that Dan Tae was hiding to get back at him. Furthermore, Seo Jin is about to be kicked out of the director position of Cheong A Art High School. Meanwhile, Seok Hoon believes there is something his father, Dan Tae, is hiding about Su Ryeon’s death.

Yoon Chul is arrested after Mr. Park confessed that he bribed him to give a fake confession. Yoon Chul admits the crime as he has no choice but to protect Eun Byeol. After hearing the news, Seo Jin runs to the police station to meet him. Meanwhile, Yoon Hee also visits Yoon Chul to tell him something she has been hiding all along.

Seok Hoon receives a phone call from Ro Na and runs to see her. When Ro Na tells him the truth, he wants to take revenge for her. Meanwhile, everyone in Hera Palace is dying to buy land in Cheonsoo District and Dan Tae is satisfied that he owns 70 percent of them as he planned for so long. However, Ae Gyo teams up with the residents to get back at Dan Tae.

Yoon Hee accepts Ae Gyo’s plan as she realizes that Ae Gyo was Su Ryeon all along. Ro Na also participates in her plan, to help her. Therefore, the police find Su Ryeon and Ro Na in the basement underneath Dan Tae’s cottage. Meanwhile, the residents are worried that Su Ryeon came back alive as they are guilty of what they’ve done to her in the past.

Yoon Hee decides to take her punishment as she feels sorry for Su Ryeon and her daughter, Seol A. However, the rest of the members of the Hera Club claim their innocence throughout the trial for Seol A’s case. Meanwhile, Logan comes back to Korea to propose to Su Ryeon, and Su Ryeon gets rid of Dan Tae’s and Seo Jin’s belongings in the penthouse.
