In the seventh episode of the tvN weekend drama “Four Hands,” broadcast on September 19, 2026, the character Choi Jeong-yo—portrayed by actor Lee Jun-young—returns to South Korea under the alias Luca Dominico, according to MediaFine. Jeong-yo’s dramatic return, following a major international conducting competition win, reveals a major plot twist: his reported memory loss regarding a devastating accident nine years prior is actually a deliberate defense mechanism designed to avoid past connections, notably with Kang Bio, played by Song Kang.
The Return of Choi Jeong-yo and the Initial Reunion with Kang Bio
According to MediaFine, Choi Jeong-yo’s sudden reappearance at a conducting competition shocks Kang Bio, who immediately recognizes him as the man believed to have died following an accident nine years ago. When Bio tracks Jeong-yo to his hotel, Jeong-yo feigns complete ignorance, claiming he does not know him. During a subsequent competition interview, Jeong-yo announces that he lost his memories and his ability to play the piano due to the past incident, sending shockwaves through the local music community.
When Bio later greets him with the words, “Thank you for returning alive,” Jeong-yo responds coldly, asking, “Why should I be thankful?” Despite this initial friction, the two cross paths again at Bio’s alma mater. Jeong-yo explains he visited the campus after reading about his past connection online and apologizes for his earlier hostility, leading Bio to guide him through familiar locations, including their old piano practice room.
The Significance of ‘Four Hands’ and Medical Realities of the Past Accident
The title of the series references “four hands,” a piano-playing style where two musicians share a single instrument, requiring deep mutual trust and synchronization. Standing before the piano, Bio finds himself unable to touch the keys, prompting Jeong-yo to ask if he is suffering from a slump. According to MediaFine, Jeong-yo reveals that his own departure from the piano stems from a gunshot wound to his shoulder that permanently damaged his nerves, making performance physically impossible rather than just a psychological slump.
Behind his return to South Korea lies a professional opportunity: accepting a guest conductor position with the Korea Symphony. However, this appointment triggers internal political battles. Kang Seung-woon, played by Jung Jin-young, orders Yoon Seo-joo, played by Seo Jae-hee, to recruit Jeong-yo at all costs. Conversely, Kang Ji-hye, played by Yoon Se-ah, opposes the recruitment to counter Seung-woon’s underlying motives, even threatening to pull organizational subsidies before Seo-joo overrides her to secure the conductor.
Uncovering the Truth Behind the False Amnesia
According to MediaFine, the episode’s closing moments deliver a definitive narrative shift. After leaving a gathering at Seung-woon’s home, Jeong-yo makes a phone call saying, “Brother, right. I remember that place. I’ll head over,” completely dropping his public persona. It is revealed that Jeong-yo watched Bio’s past interview videos beforehand and fully recognizes who Bio is, meaning his amnesia claims and cold receptions were calculated tactics to protect his privacy.
This revelation expands the central mystery of the series, shifting focus toward the unanswered questions surrounding the events of nine years ago:
- Who was originally responsible for kidnapping Jeong-yo and inflicting his shoulder injury?
- Why did Jeong-yo adopt the identity of Luca Dominico instead of seeking out his former peers?
- How will the rejected collaboration offer from Hong Jae-in, played by Jang Gyu-ri, impact Bio’s future choices?
With Jeong-yo operating with full awareness of his past, the unfolding episodes of “Four Hands” frame his return not as a tale of tragic memory loss, but as a calculated move within the competitive hierarchy of Korea’s classical music landscape.
