Kim Jung-hyun's obsession with Park Min-young reached an extreme conclusion. In episode 8 of the tvN Monday-Tuesday drama "Siren," which aired on March 24, it was revealed that Baek Joon-beom (played by Kim Jung-hyun) was the ex-lover of Han Seol-ah (played by Park Min-young), Lee Soo-ho (played by Kim Dong-jun), and his misguided love led to a horrific downfall.

The viewership rating for episode 8 recorded an average of 4% nationwide households, with a peak of 5.1%. This achievement marked the eighth consecutive time the show ranked first in its time slot among cable and general programming channels nationwide and in the metropolitan area. In the 2049 male and female demographic targeted by tvN, the show also ranked first in its time slot among cable and general programming channels both nationwide and in the metropolitan area. These figures are based on paid platforms integrating cable, IPTV, and satellite, provided by Nielsen Korea.

Han Seol-ah confirmed during a private meeting with CEO Baek Joon-beom, the prime suspect in the murders of her former lovers, that he had a close relationship with her ex-boyfriend Lee Soo-ho. When Han Seol-ah asked Baek Joon-beom if he approached her out of a desire for revenge on behalf of his close friend, he replied that his feelings stemmed from curiosity, but Han Seol-ah sensed a hidden truth in his words. In particular, she judged that Baek Joon-beom's intentions would go beyond mere revenge.

Cha Woo-seok (played by Wi Ha-joon) determined that there was something more than a typical relationship between Lee Soo-ho and Baek Joon-beom and decided to analyze their DNA information. Han Seol-ah and Cha Woo-seok aimed to obtain Baek Joon-beom's DNA at the VIP preview exhibition.

Meanwhile, Baek Joon-beom suddenly showed symptoms of respiratory distress after drinking champagne, and Han Seol-ah administered emergency treatment and handed the used syringe to Cha Woo-seok. Cha Woo-seok requested a blood analysis using this syringe. At the same time, Han Seol-ah began to suspect that Baek Joon-beom might actually be Lee Soo-ho, based on Baek Joon-beom's allergic reactions and his mentions of Lee Soo-ho.

Later, Han Seol-ah asked Baek Joon-beom, "Isn't there something you really want to say to me?" Baek Joon-beom then took her to a secret place—a two-story house located in the forest—where Han Seol-ah recalled past conversations with Lee Soo-ho. Convinced of Baek Joon-beom's true identity, Han Seol-ah emotionally called him "Suho."

Upon hearing his name, Baek Joon-beom turned around with reddened eyes and smiled, while Han Seol-ah panicked as she saw Lee Soo-ho's face overlapping with his. Baek Joon-beom's twisted desire exploded, leading to a violent struggle between the two.

After confirming that Baek Joon-beom and Lee Soo-ho shared identical DNA, Cha Woo-seok entered Baek Joon-beom's house and was shocked to find a chalkboard filled with everything about Han Seol-ah. Discovering evidence of stalking, Cha Woo-seok immediately reported it to the police, who then dispatched officers to find Han Seol-ah and Baek Joon-beom.

When Cha Woo-seok arrived at the location where Han Seol-ah and Baek Joon-beom were, he witnessed Baek Joon-beom collapsed and covered in blood, with Han Seol-ah standing beside him. Han Seol-ah, with blood on her face and in a state of panic, burst into tears upon seeing Cha Woo-seok.

Curiosity about what happened between Han Seol-ah and Baek Joon-beom is growing. The details of this incident will be revealed in episode 9 of "Siren," airing on the 30th at 8:50 PM.
