The most confusing moment is not when someone is thrown into an unfamiliar world, but when they realize that world may suit them better than expected. My Royal Nemesis Episode 4 can be read as the point where Kang Dan-sim moves beyond fearing the present day and begins to seriously disrupt Shin Seo-ri's life and Cha Se-gye's world.
My Royal Nemesis Episode 4 Story Flow
Kang Dan-sim Strikes Back and Cha Se-gye's Guard Begins to Waver
Kang Dan-sim, the notorious Joseon-era villainess, wakes up in 2026 inside the body of Shin Seo-ri and comes face to face with both the modern entertainment industry and chaebol power games. Episode 4 is an early turning point where Seo-ri's changed presence unsettles everyone around her, while Cha Se-gye grows wary of her yet becomes increasingly drawn in.
My Royal Nemesis, also introduced as Wicked World, is an SBS Friday-Saturday drama that can be checked through the official SBS program page. Based on publicly released information, it premiered on May 8, 2026, and is listed as airing Fridays and Saturdays at 9:50 p.m. International availability can be checked on Netflix.
The drama's basic premise is that Kang Dan-sim, once called a villainess in the Joseon era, wakes up in the body of unknown actress Shin Seo-ri after a poisoning crisis. In the modern world, Dan-sim encounters unfamiliar rules such as cameras, sets, managers, chaebol influence, and public image, but she quickly begins reading the situation with the instincts that once kept her alive in the palace.
My Royal Nemesis Episode 4 Basic Information
Episode 4 Story Flow
At first, Dan-sim was startled by unfamiliar modern objects and customs, but in Episode 4 she tries to use Seo-ri's situation rather than merely endure it. As the survival methods she learned in the Joseon palace start to work strangely well in the modern entertainment world, the people around her feel Seo-ri's transformation more strongly.
As an unknown actress, Seo-ri was not someone who naturally drew attention. After Dan-sim takes over, however, her speech, behavior, gaze, and attitude change completely, and people begin seeing her differently. Whether for better or worse, her presence starts to expand.
Cha Se-gye is introduced as the heir to Chail Group and the CEO of Bio J. He has controlled most situations with money, power, and rational judgment, but Dan-sim moves outside his calculations. The fun of Episode 4 lies in how the more he tries to push her away, the more he ends up paying attention to her.
Choi Moon-do is introduced as the head of Chail Construction and one of the main figures in conflict with Cha Se-gye. On the surface he appears smooth and gentlemanly, but underneath lies a strong desire to climb higher in power. After Episode 4, Cha Se-gye's personal feelings and the internal battle within the group become increasingly difficult to separate.
Seo-ri's manager, Bae Gwang-nam, is the person who experiences her altered personality and unpredictable behavior most directly. He is bewildered, but he cannot stop the change. Instead, he is left watching how Dan-sim's actions may affect Seo-ri's career.
Dan-sim and Cha Se-gye still do not trust each other easily. Yet they resemble each other in that both have had to survive at the center of power. Episode 4 presents that resemblance not as love yet, but as anger, curiosity, and an uncomfortable pull.
Character Emotion Lines
Shin Seo-ri / Kang Dan-sim
Dan-sim is not someone who fears modern society. Instead, she quickly observes unfamiliar rules and tries to turn Seo-ri's low position into an opportunity. To her, the year 2026 begins to look less like a prison after punishment and more like a new stage where she can seize power again.
Cha Se-gye
Cha Se-gye senses that Dan-sim is dangerous, but he cannot ignore how different she is from the usual people in chaebol circles and the entertainment industry. This is where his urge to control her, his curiosity, his caution, and his attraction all begin to exist at once.
Choi Moon-do
Choi Moon-do represents ambition within Chail Group. He tries to find Cha Se-gye's weaknesses, and he begins to sense that Shin Seo-ri, now occupied by Dan-sim, could become a new variable.
Bae Gwang-nam
Bae Gwang-nam is the character most often swept up in Seo-ri's transformation. Realistically he is her manager, but narratively he becomes a comic axis who observes and reacts to Dan-sim's adjustment to the present day.
Yoon Ji-hyo
Yoon Ji-hyo is introduced as a top star and stands in contrast to Shin Seo-ri. As Seo-ri's presence grows, the rivalry between Seo-ri and Ji-hyo may become even clearer.
Nam Ok-soon
Nam Ok-soon, Seo-ri's grandmother, is the family anchor that keeps modern-day Seo-ri grounded. The more Dan-sim lives in Seo-ri's body, the more her response to family relationships becomes an important emotional point.

What Episode 4 Means
My Royal Nemesis Episode 4 is not just about Kang Dan-sim adapting to the present. It is the episode where she begins moving again under the name Shin Seo-ri. Cha Se-gye cannot understand her, so he stays guarded, but that very incomprehensibility pulls him deeper into her orbit. From this point on, their relationship moves from a simple bad connection toward a space between strategic cooperation and emotional attraction.
Questions Going Forward
Will Kang Dan-sim ruin Shin Seo-ri's life, or save it?
Dan-sim's actions are risky, but they also give the once-unknown Seo-ri a kind of presence she never had before. Whether this change becomes an opportunity or a crisis will be central to the coming episodes.
Why does Cha Se-gye keep caring about Seo-ri?
Cha Se-gye sees Dan-sim as a variable and stays cautious, yet he keeps reacting to her nerve and unpredictability. Whether that reaction is simply a desire for control or the beginning of romance is one of the key points to watch.
Will Choi Moon-do try to use Seo-ri?
As the internal power struggle at Chail Group grows, Seo-ri may look like both Cha Se-gye's weakness and a new variable. How Choi Moon-do tries to use her will become important.
How will Kang Dan-sim's Joseon-era death connect to the present?
Why Dan-sim woke up in Seo-ri's body, and how the power that killed her in Joseon might be mirrored by Chail Group in the present, remain long-term story hooks.

Final Thoughts
My Royal Nemesis Episode 4 moves beyond the stage where Kang Dan-sim is simply adjusting to an unfamiliar era. It shows her trying to take control of the modern world as her own stage. She has borrowed Shin Seo-ri's body, but she is not satisfied with merely surviving. She is ready to confront again the world that recorded her as a villainess.
Cha Se-gye can no longer see her as merely a strange woman or a dangerous variable. The point where caution, curiosity, anger, and attraction all rise at once is what makes the early romance in My Royal Nemesis entertaining. From here, the major things to watch will be how far Dan-sim changes Seo-ri's life and how Cha Se-gye wavers while trying to control her.
