The Penthouse

Yoonhee's daughter dreams of becoming a classical singer. She visits the most famous soprano in Korea, Cheon Seojin. The moment when Seojin hears her voice, Yoonhee interrupts.

All of Hera Club's middle schoolers aim to top the entrance interview to Cheong A Arts High School, including Rona. The big day arrives and a surprising name tops the list - Min Seolah, a girl no one knows.

Seojin urges Seolah to give up her acceptance to Cheong A Arts High, but Seolah doesn't back down. She additionally reveals how she knows about Seojin and Dantae’s secret illicit love affair.

After Seolah's death, Rona, the first on the waiting list of Cheong A Arts High, automatically gets accepted. Yoonhee is confused at the news and tries to remember what happened the day she went to Hera Palace.

Clips of Hera Club kids harassing Seolah spread online and the Hera Club parents find ways to circumvent the situation. They decide to blame Rona and get her suspended from school. However, an unexpected man stands up for her at the emergency parent meeting.

Suryeon visits Congressman Cho to reveal the truth behind the countless orphans who were adopted but deported back. The two start arguing, and when the discussion heats up, Mr. Yoon accidentally kills Congressman Cho because he’s trying to protect Suryeon. At that same moment, the doorbell rings and Yoonhee appears.

The day Yoonhee was supposed to sell her Bosuk Village house, she sees the news of the city’s new redevelopment plan. Bosuk Village will become the main redeveloped area, bringing in a huge profit for Yoonhee and Rona.

Suryeon intentionally allows Yoonhee to see her husband having an affair with Seojin. Suryeon plans to bring down Joo Dantae, and the first step is by purchasing the building in the center of Myeongdong’s new shopping center site.

Yoonhee wins the auction bid for the Myeongdong house and Joo Dantae tries to offer a deal. However, Yoonhee states she will not sell the building to Joo Dantae.

Yoonhee moves into Hera Palace, and the whole Hera Club is in shock. Joo Dantae was the one who wrote a recommendation letter. The others scheme to kick Yoonhee and Rona out.

Yoonchul catches Seojin getting intimate with Joo Dantae, and decides for a divorce. Meanwhile, Cheong A is holding an audition to select the school's ambassador. Seokhoon subtly supports Rona, and Eunbyeol burns with jealousy.

While everyone is practicing for the Cheong A Ambassador Audition, Eunbyeol is on the verge of breaking down. Wanting to help her daughter, Seojin buys the audition script for Eunbyeol.

Yoonhee finds out how badly Joo Dantae needs to meet Logan Lee to sell the Myeongdong plot of land. She and Suryeon plan to get back at Joo Dantae by arranging Logan and Dantae’s meeting at all costs. Will Logan believe Yoonhee’s story and help her out?

At the lighting ceremony at Hera Palace, another warning calling out Min Seolah's death takes place and the Hera Club members are shocked. Seojin confronts Suryeon and exposes Suryeon’s relationship with Min Seolah.

Yoonhee finds out how Seojin used Rona and made her misunderstand Yoonhee's relationship with Yoonchul. Seojin and Yoonhee meet, with another surprise guest Seojin would’ve never seen coming.

Seojin covers up her father’s death as an acute heart attack and secures her position as the new director of the Cheong A Arts Foundation. Meanwhile, Logan Lee offers a deal to Dantae.

Yoonhee remembers that she was the one who pushed Seolah off the 47th floor. Before she could even handle the truth, Suryeon confesses how she’s been using Yoonhee to reveal the truth behind Seolah’s wrongful death.

Yoonhee sees Dantae as a chance to elevate her daughter and partners with Dantae to also hide the fact that she’s the killer of Min Seolah.

On the day of Seojin's inauguration ceremony as the new director of Cheong A Foundation, a surprise text spreads across the school. She's accused of forging Eunbyeol's admissions to Cheong A Arts High. Dantae is also sued for embezzlement and finds out Logan Lee reported him.

Seojin and Yoonhee beg to Suryeon for their wrongdoings, and Suryeon tells them to turn themselves in and pay for what they did to Min Seolah.

Yoonhee turns herself in for killing Suryeon, but there’s actually a real culprit behind Suryeon’s murder - Joo Dantae. Dantae and Seojin enjoy their freedom while Yoohee gets arrested.
