According to Korean media, actress Kim Yoo Jung has completely escaped the image of "national sister" with an impressive and shocking transformation in the newly released 19+ drama called "Dear X".
Dear X aired its first four episodes on November 6 on the Tving platform. The film revolves around the story of Baek Ah Jin (Kim Yoo Jung), a perfect star in the public eye, but behind her is a psychological wound from childhood being abused, turning her into a person who specializes in manipulating others and a desire for power, ready to destroy anyone who stands in her way.
Kim Yoo Jung was originally famous for her pure and sweet image as a "national sister" in the films "Moonlight Drawn by Clouds", "Saet Byul right House", "Girl of the 20th Century"... Recently, Kim Yoo Jung has started to build a more mature image when playing the main role in the movie "My Devil".
But it was not until Dear X that the actress really transformed spectacularly. Baek Ah Jin is a character with a contrasting appearance and personality. She has a fragile, beautiful appearance like an army, but hidden behind her is a crazy, sinister person and a dark past.
Baek Ah Jin knows how to take advantage of her natural beauty to enter showbiz, quickly rising thanks to her ability to manipulate others, she is not afraid of the tricks to eliminate those who cause obstacles.

Kim Yoo Jung's performance has conquered the audience, many people even admit that they have to " shaken" when following each eye and expression of the actress.
Kim Yoo Jung shared at the press conference that: I want to play a character who feels stressed even when I dont express emotions. Instead of expressing emotions clearly, I try to make them Empty so that the audience feels the light and scary insecurity.
This approach has been effective. In a shocking scene in episode 3, Kim Yoo Jung's character was bloodied after his father's brutal blow, but she still smiled in tears. This moment clearly reflects Baek Ah Jin's broken psychology: cold and scary on the outside, but inside, full of hurt.

Although this character specializes in manipulating and taking advantage of others for personal gain, the film also revealed that the haunting past is the source of tragedy. Behind the cruelty is a woman who was deeply hurt by abuse, violence and abandoned since childhood.
On film communities, there are many comments praising Kim Yoo Jung and the works: "Kim Yoo Jung's eyes are really scary", "I cried because of Baek Ah Jin's tragic life", "Kim Yoo Jung's appearance and acting are at a different level", "I didn't even pay attention to the time when watching the film because it was too attractive"...
After the first 4 episodes, Dear X quickly created a fever, climbed to No. 1 on the Tving platform and ranked No. 1 in countries where the show was released on HBO Max such as Thailand, Singapore, Indonesia, Malaysia, Philippines, Hong Kong (China) ...
On the IMDb website, the film is scoring a rating of 9.2/10, a rare achievement for a newly released work.
