Four Hands, Two Sonatas Builds Rivalry Through Music and Friendship
Four Hands, Two Sonatas is a South Korean drama about two young pianists.
Kang Pi O is extremely disciplined and wants his grandfather’s approval.
Choi Jeong Yo plays with strong emotion but has painful memories and serious personal problems.
The two boys first compete against each other at Korea Arts High School.
They then practice a piano piece together, which slowly helps them become friends.
Pi O begins to discover that music can be enjoyable instead of only a way to win approval.
Jeong Yo’s family troubles bring danger and make Pi O try to protect him.
The show is strongest when it focuses on the two actors and the way music connects their lives.
The Netflix drama premiered on September 4 and has released four episodes.
Kang Pi O and Choi Jeong Yo meet at Korea Arts High School and clash over their different musical approaches.
Their rivalry gradually develops into a fragile friendship through rehearsing a four-hands piano piece.
Pi O struggles with family pressure and self-doubt while Jeong Yo faces stage fright, debt-related threats, and family problems.
The leads and music are praised, though familiar school-drama tropes and slow pacing weaken some storylines.

What Works
What Does Not Work
Lead performances
What Works
Song Kang portrays Pi O as restrained, competitive, and emotionally guarded, while Lee Jun Young gives Jeong Yo an instinctive and vulnerable quality. Their contrasting performances make their scenes compelling.
What Does Not Work
The review does not identify a major weakness in the two leads, but says the broader story can sometimes make the pacing feel slower than necessary.
Story and pacing
What Works
The gradual movement from resentment and competition toward trust makes the friendship feel more believable, while the music gives the relationship a meaningful metaphor about listening and shared rhythm.
What Does Not Work
The privileged-school-student versus difficult-background-student storyline is familiar in Korean dramas, and multiple plot threads occasionally slow the series.
Use of music
What Works
Music is treated as a central part of the story rather than background decoration, and the four-hands concept reflects the characters learning to cooperate.
What Does Not Work
Some school-based sequences feel predictable compared with the more distinctive, music-driven parts of the drama.
