‘Four Hands, Two Sonatas’ Release Date, Trailer, Plot, Cast, and More Details on Netflix’s K-Drama

Song Kang is making his return to the screen, and Netflix is eager to showcase him in a captivating tale of music, pride, and heartbreak. Famously dubbed the “Son of Netflix,” Song Kang is joining forces with Lee Jun Young in the upcoming romantic K-drama ‘Four Hands, Two Sonatas,’ set to premiere in August 2026. This project marks his first significant role following his mandatory service.

The storyline may appear straightforward at first, featuring two exceptional pianists engaged in a subtle battle of talent and ego. However, the emotional depth beneath the surface is what has fans buzzing. With a talented cast, a music school backdrop, and a director celebrated for character-driven narratives, ‘Four Hands, Two Sonatas’ is poised to become one of the most discussed Korean dramas of the year.

‘Four Hands, Two Sonatas’ is a South Korean television series penned by Shin Yi-won and directed by Park Hyun-seok. The series is set to debut on August 29, 2026, airing on tvN and streaming globally on Netflix.

New episodes will be available every Saturday and Sunday at 9:10 PM KST, with two episodes released each weekend. The full season consists of 12 episodes, making it one of Netflix’s most significant Korean drama launches of the year.

International fans, including those in markets like India, will be able to stream the drama exclusively on Netflix from the same release date. An active Netflix subscription is required for viewing, and the series is rated TV-14 due to its handling of sensitive topics, language, and smoking, indicating that it is not a lighthearted campus drama despite its youthful setting.

Song Kang portrays Kang Pi-o, an elite pianist who has dedicated his life to achieving perfection. While he appears flawless and confident, he grapples with a hidden world of anxiety and pressure, a conflict that Song Kang has adeptly portrayed in previous roles.

Lee Jun Young stars as Choi Jeong-yo, a talented pianist who distanced himself from music after a challenging childhood but is drawn back into it when he encounters Kang Pi-o. Lee Jun Young comes into this role after a successful run in Netflix titles such as ‘Weak Hero Class 2,’ ‘When Life Gives You Tangerines,’ ‘Mask Girl,’ and ‘D.P.,’ generating excitement among K-drama fans.

Completing the main trio is Hong Jae-in, a viola major with an extraordinary ear for music who is on a quest for melodies that resonate deeply. Jang Gyu Ri plays Hong Jae-in, a character whose remarkable sensitivity allows her to connect profoundly with those around her, becoming a close friend and quiet support for Kang Pi-o.

The narrative centers on Kang Bi-o, a piano prodigy consistently ranked at the top in both academics and performance, hailed as a future star destined for prestigious competitions. His journey takes a turn when he meets Choi Jeong-yo, a late-blooming pianist returning to music after a difficult past, and their relationship becomes the emotional core of the series.

Netflix’s teaser showcases the duo as contrasting talents who challenge each other at the piano, but it is framed not as a simple rivalry with clear winners and losers. Instead, the story emphasizes friendship, competition, and personal growth, allowing ‘Four Hands, Two Sonatas’ to explore deeper emotional themes than typical competition dramas.

Set in an arts high school, the series follows the three leads as they navigate friendship, romance, rivalry, and personal development while pursuing their aspirations of becoming accomplished classical musicians. Rather than relying on dramatic twists, the show focuses on the emotional journeys of talented young artists striving for their dreams amid the pressures of perfection, which seems to be the heart of the story.

An official teaser has already been released, highlighting the phrase “for piano, four hands,” with Song Kang and Lee Jun Young depicted as a duo creating a single perfect melody together. Promotional clips have also emphasized this imagery, showcasing the two actors at a shared piano to hint at the emotional and musical connection between their characters.

In South Korea, the series will air on tvN, while international viewers can stream it exclusively on Netflix. Domestic fans in South Korea can also catch new episodes on TVING shortly after they air, providing an additional option to stay updated in real-time.

With Song Kang’s return and Lee Jun Young’s impressive track record, excitement around ‘Four Hands, Two Sonatas’ has only grown since the teaser’s release. Set against the backdrop of classical music, this story about pressure, identity, and connection is shaping up to be one of the most emotionally rich K-dramas of the year.

Who will you be cheering for when Kang Bi-o and Choi Jeong-yo finally sit down at that piano together—the flawless prodigy or the late bloomer reclaiming his passion for music?
