The SBS drama ‘Treasure Island’ has been dominating the ratings, taking the top spot for 8 consecutive episodes since its first broadcast, attracting great popularity. The intense retaliation of Seo Dong-ju, played by Park Hyeong-sik, has raised the immersion level even higher. The ratings have also been breaking their own records consecutively. Looking at the key points of interest, the following can be observed: Seo Dong-ju survived several near-death experiences caused by Yeom Jang-seon (played by Heo Jun-ho), but he forgot the account password containing 20 billion won of Yeom Jang-seon’s political slush fund due to amnesia. In order to regain his memory, Yeom Jang-seon killed Seo Dong-ju’s sister, Sister Agnes (played by Han Ji-hye). This leads Seo Dong-ju to regain his memory and vow revenge. Now, Seo Dong-ju is preparing to confront Yeom Jang-seon with everything he has. On the other hand, Yeom Jang-seon is a ruthless villain who would not hesitate to take lives for his goals, always aiming for ‘money.’ Everything he did, from creating the 20 billion won political slush fund he calls the ‘Patriotic Fund’ to killing Sister Agnes to retrieve Seo Dong-ju’s memories, was all for ‘money.’ Now, the three individuals will engage in a fierce power game involving the 20 billion won political slush fund and the even larger Daesan Group. It is expected to provide viewers with a tense excitement as they watch the intense battle where alliances are uncertain. Lastly, the only name Seo Dong-ju remembered when he lost his memory was ‘Sung-hyun.’ When Seo Dong-ju introduced himself as ‘Sung-hyun,’ the confusion deepened as Daesan Group’s eldest daughter Cha Deok-hee (played by Kim Jeong-nan) and secretary Gong Bi-seo (played by Seo Kyung-hwa) could not hide their bewilderment. Who is ‘Sung-hyun’? Is Seo Dong-ju ‘Sung-hyun’? If so, does it involve a secret related to Seo Dong-ju’s birth? The curiosity about the storm that the name ‘Sung-hyun’ brings is growing.
