One Piano, Two Geniuses: Song Kang and Lee Jun Young Set the Stage for a Rivalry to Remember

Some posters just make you stop scrolling — and tvN’s latest reveal for Four Hands, Two Sonatas does exactly that. Song Kang and Lee Jun Young sit side by side at a single piano, eyes closed, hands moving in perfect sync, and somehow the image says everything about the story before a single episode airs.

Song Kang and Lee Jun Young- Overview

What the Poster Tells Us?

The title itself borrows from a real musical technique — four-hand piano, where two performers play a single instrument together, blending their individual styles into one seamless piece. It’s a fitting metaphor for a story that follows two young pianists from their arts high school days into adulthood, tracing a bond that’s equal parts friendship, love, and fierce competition.

The black-and-white styling does a lot of the storytelling here. Song Kang’s Kang Bi Oh and Lee Jun Young’s Choi Jung Yo are dressed in contrasting attire, hinting at two very different personalities and emotional arcs, even as their hands complete the same song. The tagline, “One piano, two geniuses,” captures the push-and-pull at the heart of the drama — partners one moment, rivals the next, both chasing the same dream.

With both actors currently active elsewhere — Lee Jun Young in Reborn Rookie and Song Kang in Beautiful Vampire — anticipation for this pairing is already building well ahead of the August premiere.
