The Penthouse

Yoon Hee finds out how badly Joo Dan Tae needs to meet Logan Lee to sell the Myeongdong plot of land. She and Su Ryeon plan to get back at Joo Dan Tae by arranging Logan and Dan Tae’s meeting at all costs. Will Logan buy Yoon Hee’s story and help her out?

At the lighting ceremony hosted to impress Logan Lee, Joo Dan Tae faces an unexpected surprise. Another hideous warning calling out Min Seol A’s death takes place and all Hera Club members are taken aback. Right then, Seo Jin steps up to confront Su Ryeon and exposes Su Ryeon’s relationship with Min Seol A.

Yoon Hee finds out how Ro Na has been misunderstanding her relationship with Yoon Chul. She decides to get back at Seo Jin for deliberately using her daughter to instigate Eun Byeol. Seo Jin and Yoon Hee meet, with another surprise guest Seo Jin would’ve never thought of in her dreams.

Seo Jin covers up her father’s death as an acute heart attack and acts as if she had nothing to do with it. After the funeral, she secures her position as the new director of the Cheong A Arts Foundation. Meanwhile, Logan Lee offers a co-investment plan to Joo Dan Tae.

Yoon Hee scans her memory to the night when Min Seol A died. She remembers that she was the one who pushed Seol A off the balcony of the 47th floor. Before she could even handle the truth, Su Ryeon confesses how she’s been using Yoon Hee to reveal the truth behind Seol A’s wrongful death.

Yoon Hee sees Dan Tae as a chance to elevate her daughter, Ro Na’s school life. Despite feeling some guilt about slowly growing distant from Su Ryeon, she partners with Dan Tae to also hide the fact that she’s the killer of Min Seol A. Meanwhile, Eun Byeol feels disgusted toward her mom after finding out about her affair with Mr. Joo.

On the day of Seo Jin's inauguration ceremony as the new director of Cheong A Foundation, a surprise text spread across the school. She's accused of forging Eun Byeol's admissions to Cheong A Arts High and captured. Dan Tae is also sued for embezzlement and finds out it was Logan Lee who reported him.

Seo Jin and Yoon Hee both beg Su Ryeon to stop now. They can’t bear seeing their daughters suffer from their wrongdoings, now being exposed. Su Ryeon tells them to turn themselves in and pay for what they did to Min Seol A.

Yoon Hee admits to killing Su Ryeon at the police station, but there’s actually a real culprit behind Su Ryeon’s murder. Joo Dan Tae planned to frame Yoon Hee and kill Su Ryeon together with Cheon Seo Jin. The two happily enjoy their freedom as Yoon Hee gets arrested.
