Kim Young Min

With his baby face, it has often been hard for viewers to grasp the true age of the star, who is always relegated to shady ginger sidekick roles.

Kim is, in fact, 55 this year—even though the actor often plays characters in their 30s or 40s. Fans have been left astounded by his age disclosure, claiming he could pass for someone in their late 30s.

Comments from fans on social media reflect their astonishment. Not even in his 50s — one user commented, "Insane." Another added, "I don't care how you look at it; he looks 40."

More than a few seemed to share that observation, commenting on his full head of hair and how he 'looked good skin-wise.'

Here are some comments from the online community forum theqoo:

Kim's charms are undeniable, having previously played the role of Son Je Hyuk, the philandering husband in The World of the Married.

He is a stable presence within the industry, having made his stage debut in 1999 and moved into mainstream media in 2008.

Netizens are now celebrating Kim Young Min for looking younger than his age, and many opined that he was the best-looking actor amongst his peers.
