Song Kang, Lee Jun Young, and Jang Gyuri Reflect on Playing Their Characters 10 Years Later in “Four Hands, Two Sonatas”

Four Hands, Two Sonatas is entering a whole new chapter, and its cast is opening up about the challenge of aging their characters a decade into the story. With new stills revealing Song Kang, Lee Jun Young, and Jang Gyuri as 27-year-olds, fans are getting their first real look at how time has reshaped these once-teenage pianists.

The tvN drama follows the friendship, rivalry, and growth of two students who meet at an arts high school, tracking their evolution from adolescence into adulthood as professional musicians. In the latest stills, Kang Pio (Song Kang) has become a world-renowned pianist, Hong Jae In (Jang Gyuri) now works as his manager, and Choi Jeong Yo (Lee Jun Young) resurfaces at a conducting competition after mysteriously disappearing for nine years.

Song Kang explained that while Kang Pio remains fundamentally the same person, his emotional tone has shifted — describing the character’s teenage self as more sensitive and perfection-driven, and his adult self as someone who’s grown through years of lived experience.

Lee Jun Young shared that his biggest focus was making sure the character’s emotional growth across the time jump felt natural rather than forced. Jang Gyuri, meanwhile, noted that her character would have accumulated complex emotional layers by 27, shaped by sacrifice and unresolved feelings toward someone she cares for.
