A Painful Revelation in Chairman Go's Final Letter
Episode 119 hits the ground running with a major piece of family history that completely changes Go Dae-chi's perspective. After opening the final written message left behind by Chairman Go Kang-soo, Dae-chi learns that his entire identity as the blood heir of Kangsoo Group was built on an illusion. The text spells out that he was found abandoned by the estate gate on a freezing winter day, taken inside, and raised as a real son. Rather than pushing him to hoard more corporate dominance, the chairman's final plea was for him to lay down his ambition and treat people with genuine care.

For someone who spent decades acting as the rightful corporate successor, the news lands like a wrecking ball. Dae-chi storms into the main living room demanding confirmation from the household elders. His mother and butler Cho Yong-man look visibly shaken before admitting the recollection is true: they remember finding him swaddled at the entrance decades ago.

Unable to process the reality of being a foundling, Dae-chi bolts into the dawn hours. His sudden departure sparks instant panic inside the home, where his wife Eun Soo-jung dreads that he might make an irreversible decision. Relief arrives only when news filters back that Dae-chi was seen standing alone at Chairman Go's grave site, collecting his thoughts before the impending corporate event.
A Podium Shocker Derails the Kangsoo Group Inauguration
Over at the corporate auditorium, tensions run high as the strategic planning team waits behind the curtains. Go Gyeol stands ready with internal files, preparing to expose every illegal maneuver if Dae-chi takes the stage to claim the top seat. When the scheduled hour ticks past without the guest of honor, murmurs fill the room.
Then Dae-chi walks straight up to the podium in a tailored dark suit. Instead of reading the printed inauguration speech waiting on the lectern, he pushes the script aside and addresses the assembly directly.

Dae-chi systematically admits to his hidden track record. He owns up to the fatal car accident from twenty-five years ago, the systematic slush funds he built over decades, and the recent rigging of the silver town project bid. He resigns from all executive positions on the spot, announces the total societal donation of his personal shares and amassed fortune, and promises to face police investigators without resistance.

The confession pulls the rug out from everyone in attendance. When Dae-chi steps off the platform, he meets Go Gyeol in private and hands over key supporting files, urging a full and thorough inquiry. Gyeol, who spent years plotting payback, looks entirely drained rather than victorious. Watching a longtime nemesis collapse voluntarily does not bring the clean satisfaction he anticipated.

The Unresolved Exit and Go Dae-chi's Vanishing Act
Back at the estate, Go Min-ho recognizes that accepting judicial punishment is the only road left for his father to salvage any dignity, even while the family structure crumbles around them. Meanwhile, Eun Soo-jung waits in a striking gown with champagne, determined to stand by her husband and hold down the household while he serves his time.

Her unwavering stance moves Dae-chi to tears. He expresses heavy remorse, talks about untying the knots he created, and agrees to head to the precinct the following morning with family escorts.
Yet when dawn arrives, Dae-chi's room sits completely empty. There are no signs of struggle, but the man who pledged to face the law has vanished without leaving a destination.

The sudden departure presents two competing interpretations for curious viewers. One possibility is that Dae-chi buckled under the terrifying prospect of immediate prison time and chose flight over formal prosecution. Another possibility, supported by his somber farewell comments about resolving matters himself, is that he slipped away to handle unfinished business or take drastic personal action before investigators could intervene. Soo-jung collapses into tears, leaving the family scrambling to track down where he fled.
