The gripping narrative centers around Jung Se-ok, a skilled doctor whose promising career has taken a dark turn, forcing her into the underground world of illegal surgeries to make ends meet. Complicating her life further is Choi Dok-hee, played by Sul Kyung-gu, a celebrated neurosurgeon and her former mentor, now an adversary intent on sabotaging her.
Key Events in Episode 3
In episode 3, viewers witness young Choi Dok-hee during his residency, grappling with complex emotions as he prepares for an operation on his close friend, Kim Myeong-jin. Opting for another assistant, Ha U-yeong, instead of Jung Se-ok, tension brews when Jung Se-ok suspects Choi Dok-hee’s overly cordial behavior with Kim hints at deeper animosity. Determined to assert herself, Jung Se-ok cunningly maneuvers her way into the operating room, shocking Choi Dok-hee.
During the delicate procedure, an unexpected misstep causes Jung Se-ok to inadvertently wound Choi Dok-hee, forcing him to relinquish control. Seizing the moment, she completes the surgery herself. Later, in a confrontation at his office, she accuses him of deliberately sidelining her out of fear of failure while trying to protect his reputation. Choi Dok-hee, however, staunchly denies her allegations.
Climactic Moments of Episode 4
By the conclusion of episode 4, a month has passed since the surgery on Kim Myeong-jin. The stakes heighten as Choi Dok-hee ominously threatens him, demanding he warn his son about fleeing. The episode culminates in a shocking twist where it’s implied that Choi Dok-hee has taken Kim’s life.
Recap: Jung Se-ok’s Quest for Vengeance
In episode 3’s intensely wrought scenes, Jung Se-ok is discovered by Choi Dok-hee while burying Kwon Sin-gyu’s body. Despite his initial offer to assist her, she rebuffs him, insisting she’d rather die than face prison. Later, Choi Dok-hee retaliates by reporting them for illegal medical prescriptions, resulting in a month-long closure of both her pharmacy and Han Hyun-ho’s clinic.
Driven by rage, Jung Se-ok tracks Choi to Busan, where he is scheduled to receive an award. To hinder him, she proposes a surgical operation on the award founder’s son, leveraging the opportunity for revenge. Initially apprehensive, the founder, Nanae Ichida, ultimately agrees. The operation is a success, and Choi Dok-hee’s anticipated accolade remains out of reach.
In another twist, it becomes apparent that Jang Se-ok’s gamble had backing from none other than Choi Dok-hee himself, who had assured Nanae Ichida of the operation’s success, complicating their already tangled relationship.
Repercussions and Investigations
By the start of episode 4, the intrigue deepens when Jung Se-ok, still haunted by her past decisions, is found at her residence during a police investigation. When Choi Dok-hee discovers a dead body in her storage, Jung Se-ok, claiming self-defense against a stalker, navigates a precarious situation, hinting at her desperate circumstances.
As investigation activities unfold, the police unearth additional evidence at the site tied to a nurse’s remains previously discovered, engaging Jung Se-ok in a web of intrigue surrounding Choi Dok-hee’s actions. Intrigued, she seeks the truth regarding the identity of another patient believed to have replaced Kim Myeong-jin in the hospital.
Agitated and suspicious, Jung overlays her anxieties onto her investigation. She remembers the ring of Kim Myeong-jin and is cautious around the person in charge, ultimately triggering an altercation between Kim Ki-young and the staff. As they struggle near a cliff, both tumble, leading to severe injuries for Kim Ki-young.
In the final developments of episode 4, Choi Dok-hee is seen seizing a chance when discussing the nurse’s case with investigator Lee Wan-il, suggesting his growing entanglement in the narrative’s treachery. With the discovery of Rottweiler fur—a clue linking Jung Se-ok further to the crime scenes—Choi Dok-hee takes drastic actions that hint at a dark trajectory for his character and the storyline.
