In the gripping tenth episode of The Impossible Heir, titled "Trigger," the
series reaches a boiling point as the characters' actions spiral into a
whirlwind of consequences, setting off a chain reaction that threatens to upend
the delicate balance of power.

The episode unfolds with a chilling revelation: In-ha's confrontation with the chairman, who coldly discloses his intentions to disinherit him. As the chairman succumbs to a heart attack, In-ha makes the calculated decision to leave him to his fate, only for Hee-ju to arrive just in time and have him rushed to the hospital. The gravity of the chairman's condition becomes the grim backdrop against which the family's internal struggles play out.
Tae-oh's visit to the chairman's office signals the onset of a new plan, one that In-ha quickly pieces together, leading him to uncover the secret room. In-ha's discovery cements his realization that Tae-oh is a formidable adversary, one step ahead in the game of wits.
Tae-oh's strategic visit to Prosecutor Ha, the man he had framed to exonerate the chairman from embezzlement, sets the stage for a reluctant alliance. Tae-oh's promise to restore Ha's position in Seoul is met with skepticism, but Ha's eventual cooperation opens a new front in the battle for justice.
The missing evidence, cleverly concealed in a hidden folder on the mobile phone, is the key that Tae-oh needs to unlock the truth. Seonu Wan's decision to aid Tae-oh, despite witnessing his meeting with Ha, adds a layer of intrigue to the unfolding drama.
The prosecutor's success in reopening the case and Tae-oh's self-turning to the police mark a significant shift in the narrative. Tae-oh's choice to target Mo Gi-jun first, while keeping In-ha's involvement a secret, is a strategic move that underscores his cunning.
Guem-seuk's rise to power and her plan to install Seong-ju as the CEO of the group are met with resistance, as Chu Hyuk-jin, now Tae-oh's lawyer, works to aid him under the chairman's orders. In-ha's attempts to win back Park Sa-jin's favor are thwarted by Sa-jin's pragmatic assessment of the chairman's influence over In-ha's fate.
Mo Gi-jun's willingness to take the fall for the murders during the investigation is a testament to his loyalty, yet it also raises questions about the true mastermind behind the scenes.
Tae-oh's revelation of Gold H Investment to Boss Tak is a gamble that could change the tide of the power struggle. The plan, devised to make In-ha the chairman, is a bold move that In-ha himself is unaware of, highlighting Tae-oh's penchant for secretive maneuvering.
The release of Tak from prison and Hye-won's suggestion to disguise him as Gold H Investment's founder, Michael Chang, with Sunwo's involvement, adds a new dimension to Tae-oh's plan. The sudden appearance of Gold H Investment's shares in Kang Oh group is a cause for concern for Geum-seok and In-ha alike.
Tae-oh's declaration of innocence by the court is a victory, yet it is a hollow one as the true battle for control of Kang Oh group intensifies. In-ha's desperation to eliminate his father leads him to the brink of murder, only for Tae-oh to intervene at the last moment.
"Trigger" is an episode that pulls the strings of fate, setting off a cascade of events that will reshape the lives of the characters. It is a narrative that explores the depths of human ambition, the lengths one will go to secure power, and the moral dilemmas that arise in the pursuit of justice. As the story races towards its climax, viewers are left on the edge of their seats, eager to see which characters will rise and which will fall in this cutthroat game of survival.
