Actor Kim Yoo-jung (26) finished filming after falling in love with Baek A-jin.

Kim Yoo-jung recently met with Sports Chosun at a cafe in Jongno-gu, Seoul, and was interviewed for the original TVing "Dear X" (Choi Jae-won, Ban Ji-woon, scripted by Lee Eung-bok, directed by Park So-hyun). Kim Yoo-jung "I feel good because people around me also told me a lot. I'm watching it well because you captured and showed me what you wrote well, and I was happy to see the comment that the character came out well for the first time by focusing on the webtoon. Works with original works are evaluated at first in that part, and it pays a lot of attention. Baek A-jin was also a strong character in the webtoon, so I was glad that it was clearly recognized by the original fans and the new viewers."

It is Kim Yoo-jung's transformation, which is filled with favorable reviews, but he explained that he had many points of concern. Kim Yoo-jung said, `At first, I had a lot of fear and a scary feeling. There are many strong actions and expressions that the character does, so I was worried that I had to act in person, and I thought a lot about how to take the center stage without being shaken when I played this character. I wasn't the only one who thought about it, but I was able to do it with the help of the directors and the actors I worked withThere was a time when filming a scene that reached a situational limit, I fell deeply into it and couldn't get out even though I did 'cut'. When I don't remember after filming, I was surprised when I looked at the monitor, and basically even before the start, I went in with a pledge that "I should not be swayed by the person named Ajin, so it wasn't difficult to get out of it."




The perfect performance leads to a joke that he is scared to see Kim Yoo-jung. Some people said that Kim Yu-jeong "I'm scared when I meet him as a joke". My family usually doesn't see my work very well, but in "Dear X", I'm proud that the work is interesting, and people around me are enjoying it. "I hope you don't misunderstand me because Ajin is a different person from me, but I thought that the viewers who were really immersed in it could misunderstand me. Since it shows scary Ajin, the directors also jokingly said, 'What if I really trust youI once joked ' But not everything in the entertainment industry is true. Since there are many things in the story that go to extremes to make it dramatic, I hope that other characters, except for the character Ajin, will also have extreme personalities and recognize that it is less than that in reality," he said with a smile.

In addition to the effort to express Baek Ah-jin, the owner of 'Perfect Appearance', he had to portray himself becoming more and more devastated toward the second half of the play. Kim Yoo-jung "Maybe if you look at it, Ajin in the beginning and Ajin in the present are very different. As time passed, Ajin became more devastated, and as if a person were living tired, he was in such a situation and lost his vitality. To express the process, I thought a lot during filming, and there are things that come psychologically while playing the character Ajin, so I lost more weight. I don't think he was trying to recover on purpose because that's a helpful point in expressing the character Ajin."

There are also favorable reviews for Kim Yoo-jung, who persuaded viewers in this way. The audience's response to the somewhat unconventional challenge for a child-turned-child was also explosive. Kim Yoo-jung is very fortunate to be persuaded " (the transformation into Baek Ah-jin). I didn't mean to look like a femme fatale, but since Baek A-jin is such a character with such characteristics, I thought it would be nice if he could be misled by anyone in any way. I thought it would be nice if the image, the words and actions I say were naturally clear, but I'm so glad that it was expressed better on the screen than I thought. When I was thinking about playing the character Ajin, the main thing I focused on was the naturalness of sociopathic personality disorder. I didn't act out of calculation, but I felt like I didn't care about gaslighting, and I think it looked dramatic."

"Dear X", which gave a complete transformation, became a work that marked Kim Yoo-jung's acting life in his 23rd year. Kim Yoo-jung "I came to look back on myself a lot while filming this work. I also felt about various human relationships. The character Ajin thought he was affectionate in a different way, but it was expressed in the wrong way, and there were cases where it was expressed in an extreme way, so watching such a scene made me look back on 'How much can I express when I have affection for someone, and what kind of consideration should I have to engage in a relationship?' It's a grateful work and it's a work that leaves a lot of good people around. The director also said, "I think it became a memorable work because he allowed me to protect myself without being shaken by Ajin."

'Dear X' tells the story of Baek Ah-jin (Kim Yoo-jung), a woman who wears a mask to climb to the highest point from hell, and Xs who are brutally trampled on her. It topped the list with new subscribers on the weekend for three consecutive weeks on TVing, and is also doing well in the global rankings.

According to the release of the global OTT ranking aggregation site FlixPatrol on the 23rd, Viki in the U.S. topped the list for three consecutive weeks and topped Disney+ in Japan. In addition, the MENA (Middle East and North Africa) region once again proved the potential of K-content by ranking second in the top spot through StarzPlay. In addition, HBO Max is considered one of the highest performing titles among Asian works in 17 countries and regions in the Asia-Pacific, including Southeast Asia, Taiwan, and Hong Kong.
