In the episode, the character Shin Seo Ri (played by Lim Ji Yeon) is assigned a small role in an ancient costume film. Although only a little-known actress, she still boldly questioned the director and film crew, requiring the production process to comply with historical details.
Shin Seo Ri pointed to the actresses playing the queen and concubine roles, she harshly asked the assistant director: "Why do concubines wear such big wigs?
When the assistant director seemed confused, Shin Seo Ri explained: "At the time of Emperor Anjong, the ban on wigs was issued". This means that the production crew is building images of concubines that are not consistent with history.
However, her attention was completely ignored, the assistant director said that she was just an unknown actress and talked nonsense. Even the director later disregarded Seo Ri's words.
Next, Seo Ri's company rival - Yoon Ji Hyo (Lee Se Hee) - adds fuel to the fire when deliberately spreading rumors that Seo Ri "went through the back door" to get a role, implying CEO Cha Se Gye backing her.
This is inherently a situation suitable for the personality and circumstances of the character Shin Seo Ri, because in "My Royal Nemesis" she is possessed by a Joseon-era concubine, so she will have an understanding of history.
However, the unexpected film scene was discussed on forums and received many compliments.

The reason is that the movie "Perfect crown" which just ended recently has been heavily criticized for historical detail errors.
The two main actors, IU and Byeon Woo Seok, had to write a letter of apology, admitting that they had not researched and thought more thoroughly about the context and historical significance contained in the work.
On May 22, a public petition requesting the removal of the movie "Perfect crown" was officially sent to the public petition board of the Korean National Assembly.
The petitioner accused the film of distorting history, arguing that the work used royal costumes, Chinese-style terms and rituals when building the setting of a fictional modern constitutional monarchy of South Korea.
The petitioner argued that the film "seriously damages Korean cultural identity and spreads a distorted historical perception globally". The content of the petition not only requests to stop broadcasting the film but also demands the complete removal of the work from platforms.
The recommendation calls for the establishment of stronger institutional measures to prevent works accused of distorting similar cultures from appearing in the future.

Previously, the movie "My Royal Nemesis" when it started airing on SBS had to face "Perfect crown" on MBC, because both works are scheduled to air on Friday evenings - Saturdays.
At that time, "Perfect crown" was a hit movie with a rating of over 10%. But at the press conference of "My Royal Nemesis", the director of the movie declared: "Lim Ji Yeon is our competitive advantage".
On Lim Ji Yeon's side, instead of showing pressure on her opponent, she showed confidence in her project and new role.
The actress shared: "I have done everything I could for this film. Sometimes I even think: Do I really have to go so far? I have put all my ability into it. I am free to express and create everything, so I am very confident now.
