Desperation and the Battle for the Nemesis Stage
Cornered by a stalled recording contract and public scrutiny, Kang Bi-o confronts Choi Jeong-yo directly to demand a spot at the piano. Bi-o recognizes that Jeong-yo composed Nemesis out of deep-seated animosity toward him. Rather than backing away from that venom, Bi-o insists that facing the piece head-on is the only way to make the music complete.

Meanwhile, agency head Han Hyeon-jeong calls Bi-o's mother, Kang Ji-hye, delivering the harsh verdict that his contract renewal is off the table due to mounting public criticism and financial losses. The news leaves Ji-hye paralyzed with dread. She knows the truth behind past events could potentially clear the air, but stepping forward threatens to shatter whatever fragile chance her son has left at a career resurgence.

Uncovering Long-Buried Devotion and Artistic Purpose
Sensing Jeong-yo's mounting desire for payback, Hong Jae-in steps in to set the record straight. She reveals that Bi-o spent a grueling decade trying to track Jeong-yo down, even falling physically ill when rumors of Jeong-yo's death first surfaced years earlier. Jae-in warns Jeong-yo against doubting Bi-o's sincerity, planting the first real seeds of hesitation in the composer's mind.

Jeong-yo turns to mentor Kang Seung-woon to ask whether an artist can truly be separated from their moral wrongdoing. Seung-woon provides a steady perspective, reminding him that punishing a flawed creator is not their job; history and the art itself will hold anyone accountable over time. Back in the practice hall, another pianist, Min-seong, realizes Bi-o's command over Nemesis is unmatched and willingly steps aside. Jeong-yo even defends Bi-o by physically shutting down loan shark Park Se-jin, before ultimately granting Bi-o permission to debut the piece.

The Premiere Shock and the Mother's Confession
At the Hankuk Symphony 80th Anniversary Festival, Bi-o channels all his bottled-up desperation into an explosive performance of Nemesis. Jeong-yo watches from the wings, internally acknowledging that Bi-o's interpretation represents the ultimate realization of the score. Yet as thunderous applause rings across the hall, Bi-o steps toward the microphone and drops a devastating claim: he announces that he orchestrated the Prague kidnapping nine years ago and will accept legal punishment.

In the dressing room, an enraged Jeong-yo grabs Bi-o, furious that Bi-o's self-destruction robbed him of his revenge. Bi-o stays composed, making it clear that his goal was to free Jeong-yo from hatred so he could focus purely on music. Meanwhile, Ji-hye breaks down before Kang Seung-woon and confesses that she was the true mastermind who arranged the abduction in Prague. When detectives refuse to believe her because Bi-o fabricated overseas wire transfers under his own name, Ji-hye falls to her knees outside Jeong-yo's residence, begging him to save her son.

Private investigator Martin surfaces with audio evidence proving Bi-o spent five agonizing years searching for Jeong-yo, hoping against hope that his friend was still breathing. Paired with a short handwritten note on old sheet music, the evidence convinces Jeong-yo of Bi-o's innocence. After Jeong-yo recants his testimony and Ji-hye surrenders with genuine details from Wenceslas Square, Bi-o is released. Visiting his mother in the detention center, Bi-o receives her blessing to fly free from her suffocating ambition. United once more, the two prodigies sit side by side to rehearse Mozart's Lacrimosa, getting ready to share a single keyboard in true four-hands harmony.
