Treasure Island Episodes 5-6: Shocking Birth Secrets Revealed Between Cha Deok-hee and Gong Bi-seo!

The Mysterious Connection Between Gong Bi-seo and Cha Deok-hee

One of the most intriguing aspects of 'Treasure Island' episodes 5 and 6 is the mysterious relationship between Gong Bi-seo and Cha Deok-hee. The drama has been dropping hints that these two characters share a secret that only they know about Seo Dong-ju's true identity. As viewers, we've been puzzled by their complex dynamic, which seems to go beyond a typical employer-employee relationship.

The episodes suggest a shocking theory: Cha Deok-hee might actually be Gong Bi-seo's biological daughter. This revelation would explain their secretive conversations and tense interactions. According to the narrative being built, Gong Bi-seo orchestrated an elaborate baby swap years ago, replacing Chairman Cha Gang-cheon's real daughter with her own child (Cha Deok-hee) to ensure her biological daughter would inherit the Daesan Group empire.

The Great Baby Switch That Changed Everything

Episodes 5 and 6 reveal the outlines of a shocking conspiracy that occurred decades ago. It appears that Gong Bi-seo's daughter and Chairman Cha Gang-cheon's daughter were born on the same day, presenting the perfect opportunity for a switch. Motivated by ambition and the desire for her bloodline to control the powerful Daesan Group, Gong Bi-seo allegedly swapped the babies.

This means that Cha Deok-hee, who has been raised as the heiress to the Daesan Group, is not actually Chairman Cha's biological daughter but Gong Bi-seo's. Meanwhile, the chairman's real daughter grew up elsewhere, completely unaware of her true heritage. This woman later married and had a child named Seong-hyeon – who is now known as Seo Dong-ju. This makes Seo Dong-ju the biological grandson of Chairman Cha, creating a twisted web of hidden identities and bloodlines.

Yeo Soon-ho's Fatal Discovery

The plot thickens when we learn about Yeo Soon-ho, Cha Deok-hee's husband and Yeo Eun-nam's father. According to the revelations in these episodes, Yeo Soon-ho accidentally overheard a conversation between his wife Cha Deok-hee and Gong Bi-seo that exposed the entire truth about the baby switch.

Realizing the magnitude of this deception, Yeo Soon-ho made the fateful decision to reveal everything to Chairman Cha. He understood that DNA tests would prove that Seong-hyeon (Seo Dong-ju) was genetically related to Chairman Cha, while his own daughter Yeo Eun-nam would show no biological connection to the chairman. This revelation would not only expose the decades-long deception but potentially change the entire power structure of the Daesan Group.

The Tragic Accident That Shaped Their Destinies

In a dramatic turn of events, episodes 5 and 6 suggest that Cha Deok-hee, upon learning about her husband's plan to expose the truth, took drastic measures. She allegedly hired someone to cause a traffic accident while Yeo Soon-ho was driving with both children – Seong-hyeon (Seo Dong-ju) and Yeo Eun-nam – to meet Chairman Cha.

This tragic accident connects to Seo Dong-ju's fragmented childhood memories: being in a car with someone driving, and a girl wearing a Daesan Group badge sitting in the back seat. The accident resulted in Yeo Soon-ho's immediate death, while both children survived. However, Seong-hyeon suffered serious injuries and lost his memory. This is where Agnes (played by Han Ji-hye) enters the story, apparently donating part of her body for a transplant surgery that saved Seong-hyeon, who from that point forward lived as 'Seo Dong-ju.'

The Fate of Seong-hyeon's Parents

While the drama hasn't explicitly revealed what happened to Seong-hyeon's biological parents (Chairman Cha's real daughter and her husband), the episodes hint at another dark possibility. Given Cha Deok-hee's willingness to orchestrate a deadly accident to protect her secret, viewers are led to speculate that she might have arranged for Seong-hyeon's parents to be eliminated as well.

This theory would explain why Seong-hyeon became essentially an orphan who needed to be given a new identity as Seo Dong-ju. The calculated nature of these actions reveals the lengths to which Cha Deok-hee and Gong Bi-seo have gone to maintain their grip on the Daesan Group and conceal their deception from Chairman Cha.
