Actor Song Kang stars as Kang Bi Oh, a perfectionist 17-year-old piano prodigy in the upcoming tvN drama “Four Hands, Two Sonatas,” set to premiere on August 29, 2026.
Character Profile of Kang Bi Oh
Kang Bi Oh is a dedicated perfectionist who consistently ranks at the top of his class in both academics and piano studies, according to production details. Rather than relying solely on innate talent, he logs grueling practice schedules—such as a recorded 9 hours and 30 minutes in a single day—while continuously pushing past his own dissatisfaction.
According to MyDramaList, Song Kang’s character is joined by Lee Jun Young, who stars as Choi Jeong Yo. Jeong Yo is a gifted pianist who abandoned his talent following a difficult childhood before transferring to the arts high school. The arrival of Jeong Yo forces Bi Oh to confront unfamiliar limitations. The main cast also features Jang Gyu Ri as Hong Jae In, a viola major with sensitive hearing who serves as a close friend and supporter to Bi Oh. Kim Joo Heon rounds out the supporting cast as Do Hyeon Su, a teacher to the young pianists.
Production stills released ahead of the premiere highlight Bi Oh’s disciplined school routine, capturing him analyzing sheet music during breaks and accepting awards with an impassive expression. The series is directed by Park Hyeon Seok and written by Shin Yi Won.
