Song Kang and Lee Jun Young Strike a Chord in New Poster for Four Hands, Two Sonatas

The countdown has officially begun for one of this year’s most anticipated youth dramas. On July 28, tvN unveiled a brand-new poster for its upcoming music romance “Four Hands, Two Sonatas“, offering fans another heartfelt look at the evolving relationship between Song Kang and Lee Jun Young’s characters. The newly released image highlights the pair’s friendship, rivalry, and shared passion for music, while teasing the emotional journey that awaits viewers when the drama premieres later this month. With anticipation continuing to build, the latest poster reinforces why the series has quickly become one of the most talked-about K-dramas of the summer.

The title, Four Hands, Two Sonatas, is inspired by the classical piano technique known as “four hands,” where two pianists perform together on a single piano. That concept serves as both the musical and emotional foundation of the story. The drama follows two exceptionally talented young pianists whose lives become intertwined after they meet at Korea Arts High School, an elite institution for gifted musicians. As they grow from ambitious teenagers into professional performers, they experience friendship, fierce competition, personal growth, and first love while pursuing their dreams on the concert stage.

The newly revealed poster captures Kang Bi Oh (Song Kang) and Choi Jeong Yo (Lee Jun Young) dressed in their school uniforms, standing back-to-back while smiling in the same moment but expressing very different emotions. Kang Bi Oh confidently looks toward the camera with a bright smile, while Choi Jeong Yo closes his eyes as though quietly reliving a treasured memory. Although they occupy the same space, their contrasting expressions suggest they each remember that moment differently. The accompanying tagline, “The moment when notes meet, a brilliant harmony is completed,” hints that their relationship will be defined not only by competition but also by the powerful bond they create through music.

Song Kang stars as Kang Bi Oh, a perfectionist and piano prodigy whose disciplined lifestyle has made him one of the country’s brightest young musicians. Admired for his flawless performances and relentless dedication, Bi Oh appears to have everything under control until an unexpected rival begins challenging everything he believes about music and success. Opposite him is Lee Jun Young’s Choi Jeong Yo, a gifted pianist whose difficult childhood caused him to turn away from his natural talent. His arrival at Korea Arts High School reignites not only his passion for music but also a connection with Bi Oh that will shape both of their futures.

Adding another layer to the story is Jang Gyuri, who plays Hong Jae In, a viola major blessed with exceptionally sensitive hearing. Her unique musical instincts allow her to recognize extraordinary talent, making her an important presence in the lives of both young pianists. Rather than focusing solely on romance, the drama explores how three talented musicians inspire one another while confronting pressure, expectations, and the sacrifices required to pursue artistic excellence.

The series also marks an exciting return for Song Kang, whose previous performances in Love Alarm, Sweet Home, Nevertheless, and My Demon established him as one of Korea’s most recognizable leading actors. Lee Jun Young continues his impressive rise after earning praise in dramas such as Weak Hero Class 2, When Life Gives You Tangerines, and Pump Up the Healthy Love. Their pairing has generated considerable buzz among fans, with many eager to see the chemistry between two actors known for bringing emotional depth to their roles.

While earlier teasers emphasized the competitive nature of the two pianists’ relationship, this latest poster shifts the focus toward companionship and mutual growth. It suggests that despite their rivalry, Kang Bi Oh and Choi Jeong Yo may ultimately become the people who understand each other better than anyone else. That emotional complexity is expected to be one of the drama’s defining strengths, balancing youthful ambition with heartfelt storytelling.

With promotional materials continuing to reveal new aspects of the characters, excitement is steadily building ahead of the premiere. Viewers can look forward to additional teasers, character videos, and behind-the-scenes content in the coming weeks before Four Hands, Two Sonatas officially premieres on August 29 at 9:10 p.m. KST on tvN. If the latest poster is any indication, audiences are in for a moving story where friendship and rivalry come together to create a harmony neither pianist could achieve alone.
