In what could be one of the most significant crises of his career, actor Kim Soo-hyun is grappling with the fallout from serious allegations that have led to canceled advertising contracts and widespread backlash from international fan communities.

The pressures have reached such a level that his upcoming appearance at the 2025 Kaohsiung Cherry Blossom Festival in Taiwan is now at high risk of cancellation.

Originally scheduled to headline the festival on March 30, Kim's participation is in jeopardy as the controversy continues to escalate.

Reports indicate that the celebrity had been set to perform a highlight 40-minute set on the final day, and promotional products featuring his image—ranging from coffee cups to food packaging—had already been created.

However, with calls for greater accountability growing louder, the festival organizers are reportedly reconsidering Kim’s involvement.

Should the event's headliner be pulled at this stage, it's expected that Kim could incur penalties exceeding 1.3 billion won (around $990,000), marking a significant financial blow for the sought-after star.

The origins of the controversy stem from allegations linking Kim to the late actor Kim Sae-ron, specifically regarding claims of an inappropriate relationship during her minor years and accusations related to financial disputes—a situation that has tarnished his previously unblemished reputation.

As these allegations circulate, public support has dwindled, further complicating his standing in the entertainment world.

Once the face of numerous brands spanning from luxury fashion to major consumer products, Kim has seen several corporations pull back their sponsorships.

Notably, Cuckoo China—a well-known home appliance manufacturer—announced the termination of all promotional agreements with Kim through its Weibo account, stating that it would remove his images from all its platforms.

Furthermore, Jo Malone London has also decided to end its contract with the star, who was their ambassador in Asia.

The repercussions extend to Kim's ongoing projects as well.

He is currently involved in filming Disney+’s drama "Knock Off" and is a cast member on MBC's variety show "Good Day".

Both productions are under public scrutiny, experiencing mounting pressure to sever ties with the actor.

Reports indicate that "Good Day" producers have begun to reduce his airtime and that "Knock Off," with its hefty production budget, faces uncertain delays should Kim be replaced in his lead role.

As the incident unfolds, the ripples of Kim's controversy are being felt profoundly across various entertainment sectors, leading fans and industry insiders alike to question what the future holds for one of South Korea’s biggest stars.

The closing of fan communities in response to the allegations reflects a stark decline in his popularity, suggesting that Kim Soo-hyun’s once-revered status may be in peril as consumers and fans weigh in on the current events.
