In the wake of President Yoon Suk-yeol's arrest on charges related to insurrection and his controversial imposition of martial law, calls for action against First Lady Kim Keon-hee have grown louder. Opposition parties in South Korea are pushing for a thorough investigation into her alleged involvement in state affairs, casting her as a central figure in the political turmoil that has engulfed the country. Following Yoon’s detention on December 3, which left Kim alone at their residence in Hannam-dong, Seoul, concerns regarding her health have also been raised, with reports indicating she has been experiencing significant weight loss, described as being "completely skinny" by aides who visited her [South China Morning Post](https://www.scmp.com/news/asia/east-asia/article/3295183/south-korean-first-ladys-health-worsens-after-yoons-arrest-she-was-completely-skinny).

During a recent visit, ruling party lawmaker Kwon Young-jin observed the First Lady's poor state, expressing concern, "I saw the first lady. Her face looked terrible. I felt sorry for her." Opposition members are increasingly vocal about Kim's potential role in usurping Yoon's authority, with the Rebuilding Korea Party (RKP) suggesting that she could be considered a co-conspirator or the mastermind behind the alleged insurrection that has rattled the government. Kim has faced allegations of corruption, including accusations of influence over Yoon's political decisions, particularly during the last National Assembly elections, and has been referred to as "VIP No. 1" amid the escalating scandal [South China Morning Post](https://www.scmp.com/week-asia/politics/article/3294995/after-yoons-arrest-calls-south-korea-kim-keon-hee-face-charges-intensify).

As her health deteriorates, with aides noting she could scarcely eat, there are increasing demands from lawmakers to bar her from leaving South Korea while investigations continue into potential corruption. These claims are compounded by public skepticism over the couple’s reliance on **fortunetellers** to guide critical decision-making in their administration—a reflection of the pervasive spiritual influences reportedly affecting their governance. Professor Ahn Byong-jin noted that "one of the most notable aspects of the presidential couple is the persistent allegations that they rely on folk spiritual practices for decision-making," raising further questions about the legitimacy of their positions [South China Morning Post](https://www.scmp.com/news/asia/east-asia/article/3295183/south-korean-first-ladys-health-worsens-after-yoons-arrest-she-was-completely-skinny).

With Yoon now awaiting trial on serious charges, opposition parties are determined to intensify efforts to investigate Kim's alleged wrongdoings, including accusations of stock market manipulation and unethical behavior during her husband’s presidency. It remains to be seen how public sentiment will shift as the legal implications unfold for both Yoon and Kim, as their political fate—and that of the South Korean government—hangs in the balance.
