Tae-oh's strategic mind is on full display as he and his team maneuver the chess pieces of Gold H Investment. The revelation that the chairman was aware of Tae-oh's paper company adds a layer of complexity to their relationship, suggesting a deeper alliance than previously thought.

Sa-jin's discontent and his willingness to abandon In-ha if he becomes a liability underscore the fragile nature of their alliance.
The surprise revelation that Tae-oh is the co-CEO of Gold H Investment sends shockwaves through the Kang family, as Tae-oh unveils his new identity to Geum-suk, Seong-ju, and In-ha. The subsequent confrontation between In-ha and Tae-oh in the basement is a clash of wills, with both men fully aware of the high stakes.
In-ju's wife's unwitting collaboration with In-ha, who is revealed to have orchestrated his own brother's murder, adds a layer of irony to the unfolding drama. Geum-suk's dinner invitation to In-ha, which results in a tense gathering with Tae-oh and Seong-ju, is a strategic move designed to unsettle In-ha.

Geum-suk's arrest on charges of disposing of a corpse and embezzlement is a shocking development, with In-ha revealed as the informant behind the hit-and-run case.
