Article Date: November 13, 2025 / Author: Dang Huyen / Contributor: Dang Huyen
Hello, I'm Jang Young-kwan, CEO of Inside Vietnam. In this post, we've curated a selection of news from Vietnamese articles that cover Korean and global entertainment.
In recent years, Korean films and dramas that keenly explore the human psyche have been generating significant buzz on social networks. Today, we've compiled five Korean psychological films and dramas that have become major topics of discussion on online platforms. From the nature and genetics of serial killers to human experimentation, domestic violence and escape, the manipulation of ordinary citizens, and the twisted desires of female villains, these five works delve into different subjects while commonly casting a cold light on the dark side of the human mind. Let's examine each work's plot, characteristics, and which viewers they might appeal to.
Mouse (2021)
From its airing, "Mouse" relentlessly shook viewers by posing the question, "Who is the predator?" This drama tenaciously explores whether innate genes determine human evil or whether environment and choices turn a person into a monster. At the heart of the story is Jung Ba-reum, an upright and diligent police officer. Played by Lee Seung-gi, Jung Ba-reum encounters unexpected truths while pursuing a serial murder case, and as his secrets are gradually revealed, viewers are confronted with the fundamental question of "Who are the hunters and who are the hunted?"
The entire work is filled with meticulously designed twists. It employs a structure that makes it difficult to be certain who the culprit is, who the real victims and perpetrators are, until the very end, constantly prompting viewers to deduce. By intersecting genetics, criminal psychology, and ethical issues, it raises uncomfortable questions about human nature, making it a work that leaves a stronger impression when watched attentively rather than casually.
LUCA: The Beginning (2021)
"LUCA: The Beginning" creates a unique atmosphere by combining science fiction, crime, and action. A man named Ji-o, who has lost his memory and possesses superhuman abilities, lives constantly pursued by an unidentified organization. Played by Kim Rae-won, Ji-o bears traces of a secret experiment conducted on him, constantly questioning why he exists and who created him.
Lee Da-hee plays Gu-reum, a police officer who becomes entangled with Ji-o while uncovering the truth related to her parents' death in childhood. Following their respective wounds and pasts, the two eventually find themselves at the center of a massive conspiracy surrounding human experimentation. Earning the reputation of "Korean Stranger Things," this work thrillingly weaves together scientific experiments that treat humans as tools, attempts at concealment by the powerful, and the uncontrolled rampage of uncontrollable abilities. The themes of the boundary between humans and monsters and the ethics of science naturally permeate the story, leaving a lasting psychological tension.
As If You Were Beside Me (2025)
"As If You Were Beside Me," based on the Japanese novel of the same name, generated explosive buzz on social media in both Korea and Vietnam immediately after its release. Director Lee Jung-rim maintains the original work's delicate psychological depiction while maximizing cinematic tension, showing the choices of two women with cruel coldness.
Jo Eun-soo, played by Jeon So-ni, and Jo Hee-soo, played by Lee Yoo-mi, are trapped in their respective hellish realities. The two meet by chance and together contemplate the extreme option of "killing their husbands" to escape. While the film takes the form of a crime thriller, the core lies in the moral dilemma of "How far can a human go to escape a violent relationship?" The audience criticizes the decisions of the two protagonists but also understands them, and in the process, reflects on themselves and their relationships.
Manipulated People (2025)
"Manipulated People" is a psychological thriller that focuses on "How a good citizen is made into a criminal." Park Tae-jung, played by Ji Chang-wook, is an ordinary and diligent person, originally a citizen who lived more faithfully than anyone else. However, from a certain point on, inexplicable events occur one after another, and he unknowingly begins to move like a pawn on a giant board.
The film coldly depicts the process by which the wealthy and powerful thoroughly manipulate a person's life for their own purposes. Starting with small misunderstandings and false accusations, Park Tae-jung gradually finds himself at the center of an increasingly large crime, eventually becoming a fugitive. The reason it swept social networks in just the first four episodes is that the sense of helplessness, fear, and anger shown by Ji Chang-wook, along with the fear of "Could I endure in this situation?" feels realistically close. As it progresses to the latter half, he transforms from a victim being manipulated into an entity trying to regain justice himself, delivering intense catharsis.
Dear X (2025)
"Dear X" is a powerful and controversial work that has been described as "the darkest Korean psychological film of the year" on social networks in 2025. Star Baek Ah-jin, played by Kim Yoo-jung, grew up enduring constant abuse from childhood and eventually becomes a cold top star who dominates the entertainment industry. The film is not a commonly seen victim narrative but psychologically follows how a person with victim experiences moves to the position of perpetrator.
Baek Ah-jin keeps four boys by her side, identifies their weaknesses and wounds, and begins to manipulate them one by one. As the boundaries between love and obsession, protection and control continue to blur, the audience experiences being captivated by this female villain without realizing it. Although there are many violent scenes and psychological pressures, it goes beyond simple cruelty and leaves the question of "Why was such a broken human being born?" Kim Yoo-jung's cold eyes and the bizarre atmosphere of "the more evil, the more beautiful" are praised for enhancing the work's perfection.
The Lingering Impact of Korean Psychological Films
The five works introduced here, "Mouse," "LUCA: The Beginning," "As If You Were Beside Me," "Manipulated People," and "Dear X," commonly focus on the inner lives and choices of characters rather than flashy action. Although they feature different characters such as serial killers, psychics, victims of domestic violence, manipulated citizens, and female villains, their situations and emotions raise the question for viewers, "Would I have made a similar choice?" The reason these works have generated such a strong reaction on social networks is because of this immersion and the topics they provide for discussion. If you like the psychological thriller genre, we confidently recommend all five works as worthwhile choices to watch attentively.
