A Shocking Reappearance in Brno and the Cold Shoulder
The seventh hour wastes zero time dropping emotional landmines. When the newly crowned Brno conducting champion Luka Domenico turns out to be Choi Jeong-yo, who vanished without a trace nine years back, Kang Bi-o sprints through Czech streets trying to catch a departing taxi. Tracking his childhood friend to a local hotel room, Bi-o is ready to pour his heart out in relief. Instead, he runs headfirst into an icy brick wall. Jeong-yo claims total amnesia from the trauma of his disappearance, bluntly shuts down every inquiry about their shared past, and flatly refuses Bi-o's plea for a simple embrace.
Back home in Seoul, news travels fast. Kang Seung-woon catches footage of the conducting competition and immediately alerts Hankuk Arts High School board chair Yoon Seon-joo. The classical music establishment instantly starts scheming over how to handle the sudden return of someone long written off as dead.

Old Memories in the Rehearsal Room and a Tragic Confession
Jeong-yo soon arrives in Seoul to field a guest conductor offer from the Korea Symphony Orchestra. His first stop is not an executive office, but their old high school stomping grounds. When Bi-o crosses paths with him on campus, Jeong-yo offers an unprompted apology for his harsh defense mechanisms back in Europe. Bi-o takes the olive branch and guides him straight into the four-hands practice room where they spent countless hours sharing a single piano bench.
Jeong-yo quickly reads Bi-o's stiff posture and evasive excuses about hand pain as an obvious performance slump. In response, Jeong-yo explains his own grim reality. Nine years earlier, a gunshot wound to his right shoulder damaged the motor nerves in his hand, leaving him functional for daily life but permanently unable to perform onstage. Switching to conducting was his only way to stay connected to music. Playing a Brahms piece using only his left hand, Jeong-yo challenges Bi-o to recognize that a psychological slump, unlike irreversible nerve trauma, is something Bi-o still has the power to overcome.
Secret Investigations and the Ultimatum in the Study
Jeong-yo's return sends shockwaves through Bi-o's household. Bi-o's mother, Kang Ji-hye, visibly trembles with anxiety and guilt after finishing church volunteer duties. She pleads with Seung-woon to block Jeong-yo from entering the orchestra, dreading that Bi-o will once again be overshadowed. When Ji-hye threatens to pull public subsidies, Yoon Seon-joo stands firm, willing to forfeit government funding to secure the commercial draw of a star maestro.
Meanwhile, Bi-o suspects foul play behind the events of nine years ago. Working through a private contact from his darkened room, Bi-o secretly orders a quiet inquiry to unmask whoever commissioned Jeong-yo's abduction.
The tension peaks during a formal gathering at Seung-woon's study with Bi-o, Jeong-yo, Ji-hye, and Hong Jae-in. When Seung-woon questions whether Bi-o's troubled hands can handle a concert, Jeong-yo drops a bombshell. He flatly refuses to consider any other soloist, insisting that his debut concert will only happen with Bi-o at the piano. Overwhelmed by what feels like public pity, Bi-o refuses and walks out.
As Jeong-yo steps outside, the episode pulls off its biggest twist. Getting into a car, Jeong-yo casually takes a phone call in fluent Korean, demonstrating that his amnesia is an elaborate disguise. Through a private flashback, we learn his true goal: knowing his own right hand is lost forever, Jeong-yo deliberately made himself the provocateur, willing to serve as raw kindling to reignite Bi-o's dormant musical fire.

No, Jeong-yo's memory loss is a deliberate cover story. The final scene confirms he remembers his past clearly and is putting on an act to navigate industry politics and force Kang Bi-o back onto the stage.
Why does Kang Bi-o reject Jeong-yo's offer to perform together?
