Before they’re rival pianists battling through adulthood, they’re just two nervous teens in school uniforms. tvN’s new making-of video for “Four Hands, Two Sonatas” gives fans their first behind-the-scenes look at the drama’s poster shoot — and it’s full of unexpected charm.
What The Making-Of Video Shows
The video captures Song Kang and Lee Jun Young posing together for the drama’s official poster, while Jang Gyuri tests out the piano on set, growing shy once she notices the camera and insisting, “I’m actually good at playing the piano.” Later, dressed in a school uniform, she jokes that it feels less like yesterday and more like an entirely past life.

What “Four Hands, Two Sonatas” Is About
The title refers to the piano technique where two people play a single piano together, and the drama uses that as its central metaphor. It follows Kang Pio (Song Kang) and Choi Jeong Yo (Lee Jun Young), who meet at an arts high school and grow from teenage friends into professional pianists, tracking their friendship, rivalry, and romance across the years.
Why This Preview Works
Making-of content like this does more than hype a premiere — it humanizes the leads before the drama’s higher-stakes storyline kicks in. Seeing Song Kang and Lee Jun Young goof around in uniforms, paired with Jang Gyuri’s candid piano moment, sets an emotionally grounded tone that fits the show’s coming-of-age structure, making the eventual shift into adult rivalry hit harder.
