Dive into the Dark World of Kim Yoo-Jung's New Thriller "Dear X"

The upcoming K-drama Dear X is already creating waves online with its chilling concept and powerful cast lineup. Set to premiere globally on HBO Max this November, the series exudes strong crime documentary vibes from its trailer, which is intense, mysterious, and eerily real.

A Gripping Storyline

Based on the popular webtoon of the same name, Dear X dives into the mind of a seemingly perfect woman who hides dark secrets behind her smile. The story’s gritty tone and unconventional heroine make it one of the most anticipated thrillers of 2025.

Synopsis

The story centers on Baek Ah-jin (played by Kim Yoo-jung), a beautiful yet manipulative woman who has mastered the art of deception. Her charming exterior hides a twisted personality and a history of calculated crimes. But her carefully built world begins to crumble when journalist Yoon Joon-seo (Kim Young-dae, Perfect Family, 2024) starts investigating her mysterious past.

What makes Dear X unique is that it doesn’t try to justify the lead’s actions with a tragic backstory — Ah-jin is simply unapologetic and terrifyingly real. The show’s tone feels like a cross between a true-crime documentary and a psychological thriller, capturing the tension between obsession, love, and manipulation.

Cast of Dear X

The drama features a powerhouse lineup. Kim Yoo-jung returns in a bold new avatar, completely breaking away from her sweet image to play one of her darkest roles yet. Opposite her, Kim Young-dae shines as the determined reporter tangled in her web of lies.

Supporting roles include Kim Do-hoon, known for Moving, and Lee Yul-eum (Nevertheless, 2021), who add more mystery to the already complex storyline. Together, the cast perfectly balances intensity with emotion, making every scene unpredictable and gripping.

Fans’ Reaction and Why It’s Worth Watching

Fans have been buzzing about the trailer since its release, praising Kim Yoo-jung’s transformation and the show’s bold storyline. Many are calling it the return of dark, stylish thrillers — something K-dramas have been missing lately. The eerie cinematography and unsettling background score only add to the “criminal documentary” feel that makes it so addictive.

If you loved dramas like Eve, Revenge of Others, or Remarriage & Desires, this is a must-watch! Dear X promises a mix of psychological depth and pure chaos, showing that sometimes the villain can be the one we root for!

Final Thoughts on Dear X

With its haunting visuals, complex characters, and unpredictable plot, Dear X looks ready to redefine the psychological K-drama genre. Kim Yoo-jung’s chilling performance alone is enough reason to tune in, but the entire setup, from the direction to the production design, screams perfection.

Would you root for a psycho heroine like Baek Ah-jin, or fear her instead?
