In a world where success and reputation mean everything, Hwang Hyunjin stands as the epitome of charm and grace, loved by everyone around him. He's a K-pop idol celebrated for his mesmerizing stage presence, kind smile, and flawless public image. However, behind this mask lies a twisted mind with a fascination for manipulating others.

As a "people collector," Hyunjin subtly isolates his chosen victims, worming his way into their lives to gain their trust and admiration, only to shatter them emotionally and psychologically when they least expect it. His fan base unknowingly fuels his ego, providing the perfect cover for his darker obsessions. Only a few people in the industry start to notice that those who get too close to him end up ruined, struggling with mental breakdowns and estranged from others.

One young trainee catches on, noticing Hyunjin’s odd patterns and decides to investigate, determined to expose his true nature. But Hyunjin catches wind of this pursuit and starts his own psychological game, planting seeds of doubt and paranoia in the trainee’s mind. The line between reality and Hyunjin’s carefully constructed illusions blurs as the trainee becomes trapped, questioning their own sanity.

As Hyunjin’s dark side becomes more pronounced, the stakes rise. The trainee must navigate his web of deception and find a way to reveal the truth before Hyunjin’s charm—and his hold over the public—completely destroys them both.
