Two pianists. One rivalry. A friendship tested by ambition. tvN’s upcoming drama “Four Hands, Two Sonatas” just dropped its first character posters, and they’re already setting the emotional tone for what’s shaping up to be a beautifully intense coming-of-age story.
What the Drama Is About
The title borrows from a real piano term — “four hands” refers to two people playing a single piano together. Fittingly, the drama follows the friendship, love, rivalry, and growth of young musicians who meet at an arts high school, tracing their journey from adolescence into adulthood as professional pianists.
Meet the Characters
The new posters spotlight three central figures:
- Kang Bi Oh (Song Kang): A perfectionist loner shown deep in thought at the piano, his gentle touch on the keys hinting at meticulous, delicate musicality.
- Choi Jung Yo (Lee Jun Young): A “wild genius” pianist with sharp eyes and quiet resolve, whose sheet music is covered in personal interpretations — someone who trusts instinct over the textbook-correct answer.
- Hong Jae In (Jang Gyuri): A violist with perfect pitch and an elegant, warm presence, expected to be the one who first recognizes the raw talent in both Kang Bi Oh and Choi Jung Yo.

Why This One’s Worth Watching
Music dramas live or die on chemistry, and pairing a “perfectionist loner” against a “wild genius” sets up a classic rivalry-to-respect arc that fans of shows built around competitive artistry — think dance or classical music dramas — tend to love. Add Jang Gyuri’s character as the emotional anchor with an ear for talent, and the show has all the ingredients for a compelling ensemble dynamic.
