Kim Yoo Jung's performance in the psychological thriller "Dear X" is causing intense debate among audiences, many of whom are calling this her most beautiful and striking onscreen role to date. The drama has rapidly become one of the hottest Korean shows in conversation right now.

The show has captivated the audience with its intricate character psychology, unexpected turns, and powerful performances from the cast. Recently, the focus has shifted to Kim Yoo Jung's portrayal of the protagonist, Baek Ah Jin. The drama has rapidly become one of the hottest Korean shows in conversation right now.

In a red-carpet scene from the latest episode, "viewers were overwhelmed by the way Kim Yoo Jung transformed into a top star." Immediately after her appearance, her styling, hairstyle, and makeup turned heads.

On the online community theqoo, discussions intensified as fans highlighted the actress's visual impact. Many comments said that "Kim Yoo Jung is unprecedentedly beautiful and that this is her most beautiful appearance on screen."

Some fans even recommended hiring the drama's stylist for real life because, even as a highly recognized naturally beautiful actress, many of her real-life red-carpet moments often receive divided opinions. According to Laodong, when she attended the 2025 Busan International Film Festival, some commented that her outfit was unflattering to her age and figure.

By contrast, "Dear X" offers Kim Yoo Jung as a fashionable, sensual, and confident character—what many fans consider an image that truly shows off her strengths. Though Baek Ah Jin was supposed to be a villain, viewers confessed they "couldn't stop loving her" due to her stunning look and charismatic appearance.

The traumatic conditions of her upbringing, which included parental neglect and abuse, are responsible for making the character manipulative. Sharpness of personality and exploiting others have made her one of the most complicated figures in this drama.

The most shocking scene involves Baek Ah Jin asking Jun Seo, who has loved her since he was a child, to help her date her co-star Heo In Gang. Knowing this, she is emotionally detached and self-serving.

In the past interview, Kim Yoo Jung shared her initial hesitation about her role. A neutral sentence introduces her words: "Baek Ah Jin is a very difficult character to play, so I was a bit scared if I accepted."

She says that after consultation with the director, she felt confident, and thus, she took on the role. "He explained in detail why I was the right person to play Baek Ah Jin."

Fans and critics alike now say this role is a major milestone, marking Kim Yoo Jung's ability to break away from the long-held "national sister" image. Her well-received performance has placed Baek Ah Jin among the most memorable characters with personality disorders in Korean television.
