Netflix’s Korean coming-of-age drama Four Hands, Two Sonatas is now streaming on Netflix after its August 29, 2026 premiere. Song Kang plays elite piano prodigy Kang Pi-o, while Lee Jun-young plays late-blooming pianist Choi Jeong-yo. The live Netflix title page now adds Jang Gyu-ri, Yoon Se-a, Kim Ju-hun and other supporting actors that were absent from the first announcement.

Four first-party sources were rechecked on September 12. Netflix’s newsroom and official videos establish the premise and August 29 launch; the live title page confirms current availability, the creators and the expanded cast. Netflix still varies ratings, subtitles and dubbing by account territory.

What Netflix has confirmed

Netflix’s July 16 announcement places the story at an elite arts high school for young musicians. The two pianists are not presented as simple opposites who meet only for a final competition. Their rivalry, friendship and shared focus on the piano repeatedly pull them into each other’s lives.

The current official fact sheet is short but clear:

Cast and character guide

Song Kang — Kang Pi-o: Netflix describes Pi-o as an elite prodigy who appears confident and perfectly trained. Under that surface, however, he is carrying anxiety, pressure and an intense fixation on music. The official description gives him an internal conflict rather than treating talent as effortless.

Lee Jun-young — Choi Jeong-yo: Jeong-yo is a later-developing pianist who continues toward music after a difficult childhood. Netflix characterizes him as free-spirited, direct and warm. His route to the piano contrasts with Pi-o’s more structured path.

The live Netflix title page lists Jang Gyu-ri, Yoon Se-a, Kim Ju-hun, Jung Jin-young, Seo Jae-hee, Kim Hye-hwa, Kim Min and Lee Myeong-ro alongside the two leads. It also credits creators Park Hyeon-seok and Shin Yee-won. These names come from Netflix rather than an unofficial cast database.

What the official teaser actually shows

The 37-second Netflix K-Content teaser centers on the two leads at the keyboard and frames their relationship through competition and mutual challenge. Netflix later published a full official trailer on August 11, giving viewers a longer first-party preview without relying on reaction uploads or reposted clips.

The official videos do not establish the ending, a final contest winner or a universal episode schedule. Claims beyond the footage and Netflix’s text were not treated as confirmed in the September 12 check. The embedded video is preferable to reaction uploads because its title, channel and publication context are directly attributable to Netflix.

How to watch and check local availability

The series has passed its August 29 premiere date and the official Netflix title page is live. Availability details should still be checked inside the account that will actually watch it because ratings, audio, subtitles and even title-page presentation differ by region.

Use this order:

  1. open the official Netflix title page or search the exact English title in the app;
  2. confirm that the account’s region displays a play option rather than a reminder or unavailable notice;
  3. open Audio & Subtitles to verify the languages available to that account;
  4. check the displayed maturity rating, which is not universal; and
  5. use Netflix’s in-app episode list as the source for the currently available episode count.

What remains unknown

The public, signed-out Netflix title page confirms the cast, creators, genre and regional maturity rating, but it does not expose a universal episode total, per-episode runtime, or every territory’s audio and subtitle inventory. Those account-specific details should not be inferred from another country’s page. This guide also does not reveal competition outcomes or later relationships.

The current practical answer is: the series is available now; Song Kang and Lee Jun-young lead; use the official title page inside your own account for the exact episode, language and rating information.
