[Edaily Starin Choi Hee-jae Reporter] As “Four Hands” members Song Kang and Lee Jun-young prepare for their collaboration, they exude a sharp sense of tension.

In Episode 9 of tvN’s Saturday-Sunday drama “Four Hands,” set to air on the 26th, conductor Choi Jeong-yo (played by Lee Jun-young) continues his harsh reprimands, while pianist Kang Biao (played by Song Kang) and his manager Hong Jae-in (played by Jang Gyu-ri) show signs of discomfort.
Kang Bi-o, Choi Jeong-yo, and Hong Jae-in—who were inseparable friends during their school days—have maintained their bond even as adults in their late 20s. Kang Bi-o performed as the pianist for Choi Jeong-yo’s debut concert as a conductor, marking his return after nine years, while Choi Jeong-yo helped Kang Bi-o overcome his creative slump. Hong Jae-in also praised their music and actively supported their collaboration.
However, ahead of this joint performance, an uneasy atmosphere begins to linger among the three. Choi Jeong-yo suddenly applies a strict standard to Kang Biao’s playing and delivers a series of sharp criticisms, leaving not only Kang Biao but even Hong Jae-in puzzled.
As curiosity mounts over why Choi Jeong-yo suddenly reacted so sharply, newly released photos capture the serious atmosphere of the trio’s rehearsal session. A tense standoff hangs in the air between Choi Jeong-yo—sitting without a trace of a smile and gazing at Kang Bi-o—and Kang Bi-o, who stares back at him with a cold expression.
Hong Jae-in’s reaction also catches the eye, as she was the one who had cheered for and welcomed Kang Biao and Choi Jung-yo’s duet more than anyone else. Hong Jae-in, who always smiled whenever she heard the two sing in harmony, is now watching the situation closely with a frown.
We eagerly await the full story: What exactly prompted Choi Jeong-yo to shower Kang Bi-o with harsh criticism, and will the unexpected discord that has arisen between the three of them be resolved without incident?
“Four Hands” is a drama that portrays the friendship, love, competition, and growth of young people who meet at an arts high school filled with musical prodigies. Actors Song Kang and Lee Jun-young star in the series. It airs every Saturday and Sunday at 9:10 p.m. on tvN.
