Over its official Instagram, SBS released a series of intriguing still cuts featuring Bae Ro Na and Cheon Seo Jin.

Intense Confrontation between Bae Ro Na and Cheon Seo Jin

Based on the teaser, Oh Yoon Hee's (Eugene) only daughter bravely confronted the newly hailed ​​Cheong-Ah Arts School director.

It appears that the intense conversation between the two was about the truth behind her mother's tragic mother and the testimony of Cheon Seo Jin's daughter, Ha Eun Byul, played by Choi Ye Bin.

"'Ma'am, I'm never giving up.' Ro Na doesn't bat an eye in front of Seojin," the caption reads.

"Penthouse 3" Episode 6 Recap: Cheon Seo Jin Killed Oh Yoon Hee

To recall, the "Penthouse 3" episode 6 revealed that it was the former primadonna who killed Oh Yoon Hee.

At the time of Ha Eun Byul's near-death experience, she recalled the unpleasant past that they had, which triggered her emotions.

Due to her desire to get revenge towards Oh Hoon Hee, she pushed her off the cliff. Unfortunately, the shocking scene was witnessed by Ha Eun Byul.

There, she mentioned how she despises her mother, saying that she killed the woman who tried to save her.

On the other hand, Bae Ro Na knew that her mother's death was not just caused by a mere accident.

To uncover the truth behind her death, she seeks Ha Eun Byul's help, who is the sole witness at the time of the incident.

However, Eun Byul shunned Bae Ro Na's plea and pointed out that it was Oh Yoon Hee who abducted and tried to kill her.

Little did she know that her tutor, Jin Bun Hong (Ahn Yun Hong,) injected a drug that would erase Eun Byul's memory of the incident.
