### Stardom, Rumors, and Jae-in's New Role
Nine years after the disappearance of his fellow pianist Choi Jeong-yo, Kang Bi-o sits at the summit of the classical music world. He sells out premier venues like Singapore's Esplanade, backed by his longtime close friend Hong Jae-in, who steps in as his dedicated manager.
Yet beneath the applause, Bi-o lives with persistent dread. At a reception, an acquaintance corners him with dark rumors claiming Bi-o was somehow connected to Jeong-yo vanishing nearly a decade ago. The casual accusation freezes Bi-o in his tracks.
Jae-in tries to cut through the heavy mood with playful banter on the night walk back. She treats her management position with genuine affection, trying to be the steady anchor Bi-o desperately needs. Still, his inner turmoil keeps him from letting his guard down completely.
### Dead Ends Across Romania and Moldova
Just after a gala performance, Bi-o receives an urgent alert from private investigator Martin. A refugee in Romania claimed to have met Choi Jeong-yo, reporting that the man suffered severe hand injuries and could no longer play piano.
Bi-o skips his post-show commitments and rushes directly to Romania to follow the lead himself. But an extensive port search turns up crushing news: the injured man merely shares the same Korean name. After five continuous years of chasing phantom leads across Europe, Bi-o collapses against a brick alley in pure exhaustion. When Martin points out that international authorities long considered the case closed, Bi-o is forced to confront whether he seeks Jeong-yo's survival or just an end to his own guilt.
Back at his hotel, an intoxicated Bi-o pleads with Jae-in to stay by his side until he drifts to sleep. Jae-in watches him rest, quietly acknowledging that her lighthearted declarations of loyalty were completely earnest.
A sudden development shifts the investigation to Moldova, where kidnapping suspect Andrei Ceban has just been released from prison. Bi-o meets Ceban in a run-down bar. The suspect taunts Bi-o, boasting that he eliminated Jeong-yo and demanding a massive payoff to reveal who hired him. Bi-o races to the nearest international bank to withdraw the funds. By the time he hurries back, sirens fill the street: Ceban was fatally struck down during a bar brawl, destroying the last direct lead to the conspiracy.
### Collapsing on Stage and the Surprise Maestro
Overcome with sorrow in a dingy room in Moldova, Bi-o breaks down in front of Jae-in. He confesses the crushing weight he carried for nine years after claiming the competition victory meant for Jeong-yo. Jae-in holds him tight and promises never to leave his side.
Returning to Korea brings no relief. Family pressure mounts between his grandfather's cold dismissal and his mother's relentless expectations. Preparing for a nationwide recital tour, Bi-o relies on medication in his dressing room just to settle his shaking nerves. He confronts his former teacher Hyun-soo, venting bitter resentment that everyone grieves the missing prodigy while ignoring his own slow unraveling.
The breaking point hits during a major live concert. As Bi-o plays, a vivid hallucination of Jeong-yo appears seated in the audience. Panic strikes, and Bi-o halts mid-performance before fleeing the stage.
Unable to touch a piano lid afterward, Bi-o follows Jae-in's advice and visits a therapist, who encourages him to face his grief and let go. He travels to a quiet European city for solitary reflection. Wandering into a historic concert venue, he hears an orchestra performing with fierce passion.
Standing on the podium with baton in hand is Choi Jeong-yo himself. The presumed-dead prodigy didn't perish—he rebuilt his musical life as a commanding conductor. A stunned Bi-o shouts Jeong-yo's name and bolts toward backstage as the episode ends on an electrifying cliffhanger.
