Kim Soo Hyun's career took a nosedive after serious allegations popped up on the internet.

His highly acclaimed reputation faced serious allegations and negative rumors, with severe backlash from fans and industry insiders.
Soon after the scandal broke, Kim Soo Hyun lost nearly a million Instagram followers.
The rapid fall from grace reflected a growing doubt among his fanbase, which the severity of the allegations has only deepened.
During the controversy, the likes of luxury brands Prada severed links with Kim Soo Hyun.
Attracting attention was the immediate impact on the economy with those high-profile exits highlighting his sullied name.
Viewers were not kind at all to recent episodes of Kim Soo Hyun on the variety show "Good Day." Netizens demanded his removal, leading to minimized screen time before he was ultimately dropped from subsequent episodes.
A longtime friend of Kim Soo Hyun, Jung Hae In faced mounting demands from fans to unfollow the embattled actor.
Despite pleas to distance himself, Jung Hae In continued posting on Instagram, attracting criticism for maintaining the public friendship.
Nonetheless, some actors have appeared to distance themselves from the actor as follows:
Im Si Wan

Another close friend, Iim Si Wan, experienced similar backlash.
Accused of supporting Kim Soo Hyun, he subsequently unfollowed everyone on his Instagram except his agency, a move widely interpreted as a bid to dodge controversy.
Ahn Bo Hyun and Seol In Ah

Ahn Bo Hyun and Seol In Ah, both of whom once followed Kim Soo Hyun, removed everyone from their follow lists.
Their decision, coming soon after the scandal erupted, was interpreted as a clear attempt to avoid the fallout.
Choi Woo Shik

Comments from a 2014 interview with Choi Woo Shik resurfaced, revealing he had heard negative things about Kim Soo Hyun.
That revelation renewed debate over whether anyone in the industry had suspected Soo Hyun's behavior previously.

Kim Ji Soo

Actor Kim Ji Soo, himself once embroiled in controversy, clarified he had never met Kim Soo Hyun. Followers interpreted this as Kim Ji Soo's attempt to distance himself publicly from the scandal.
