"Play the piano again" Jeong Yo's final request, a sacrifice and musical bond toward Kang Bi-o

The story of two individuals entangled in an obsession and longing for music has come to a close. In the final episode of tvN's 〈Four Hands, Two Sonatas〉, the process of Kang Bi-o, who was planning to give up the piano, standing before the keys again through Jeong Yo's sacrifice and sincere encouragement was portrayed.

"You were the light to me"... The sincerity of Jeong Yo faced by Kang Bi-o

In the video, Kang Bi-o faces an unexpected situation prepared by Jeong Yo to make him play the piano again. Leading Kang Bi-o back to the piano, Jeong Yo mentioned Kang Bi-o's existence, which had become the light and hope of his life in the past. Although Kang Bi-o wandered between a desire for revenge against Jeong Yo and feelings of guilt, he confirms the sincerity of Jeong Yo, who saved him through music. Kang Bi-o confessed to Jeong Yo, saying, "You made me feel ashamed of myself for intentionally trying not to be serious in front of music," and stated that it was Jeong Yo who led him toward music when he was in despair. Jeong Yo mentioned that he had bought a piano again, thinking it would be necessary if Kang Bi-o were to play again, and requested Kang Bi-o to play the piano again, saying, "I don't know about other things, but at least shake off the guilt toward me." Jeong Yo emphasized that Kang Bi-o's performance was a performance completed by his own interpretation, and along with a proposal to play Bach Cantata No. 160 together, he assigns the role of Primo to Kang Bi-o.

Jeong Yo's choice risking hand paralysis and the letter left behind

Jeong Yo leaves, leaving a final request to Kang Bi-o not to give up on music. According to the subtitles and dialogue in the released video, Jeong Yo reveals through a letter left to Kang Bi-o that the reason he was obsessed with revenge was that he missed the days when they played the piano together in the past. He conveys his intention to leave not to express resentment and hatred, but to make music that consoles someone, leaving a message that he hopes Kang Bi-o grows into a good musician. Through the letter, Jeong Yo says goodbye, leaving words that by the time this letter is discovered, he will no longer be there.

The weight of Jeong Yo's actions is revealed through the reminiscences of a character appearing later. According to the dialogue of the character in the video, Jeong Yo was suffering from a disease where the motor functions of his hands were gradually paralyzing due to brachial plexus injury caused by a past shoulder injury. It was revealed that Jeong Yo's longing for music was so great that he demanded an injection, saying he had something he absolutely must do, despite concerns that he could permanently lose the use of his hands if he were to receive an overdose. Subsequently, news is delivered that Jeong Yo retired without coming to the hospital, suggesting that the choice he made for Kang Bi-o was a sacrifice for their musical bond.
