O Rei de Porcelana (2021)

Hong Shim's family is brutally murdered with the exception of her and her older brother as they escaped. They're later separated as her brother hides her and uses himself as bait to lure away the people sent to kill their family away from her. He ends up being caught and is forced to work for the same person who kills his family in order to protect his sister. Crown prince Lee Yul or Won Deuk (the name he is given by Hong Shim's adopted father after he finds him with his memories gone) set a decree as a crown Prince before losing his memories that every single woman 28 and older must marry. And because of this law combined with his memory/ identity loss, he becomes Hong Shim's husband due to a lie her father spun out and she played along with to avoid being flogged.

Zhu Yan Zhi, disguised as a man, seeks to learn martial arts with an elite clan. Once she begins her intense training, Zhu finds herself at odds with her trainer and superior, Liang.

Miki Ogawa yearned to live the life of a lovely girl and moved to the city from the countryside because of this. She holds a job at a fashion mail order company. Miki Ogawa also has a secret. She is transgender. Although she has a pretty woman's appearance, her sex is male. One day, Tadaomi Goto appears in front of Miki Ogawa. They graduated from the same high school. Tadaomi Goto is flustered by Miki's different appearance, but they happen to become roommates.

Both shows share the same energy and a few of the same actors. Please watch both to be the judge? It's almost canny. I get a sense of where the show will go based on similar dramas, but Mr. Queen definitely gives the same vibes.

Set in 1398. Kim Min Jae is the supreme commander of the Joseon Dynasty. He falls in love for the first time and for that woman he takes risks.
Yi Bang Won is the King’s son. He helped his father set up the Joseon Dynasty era, but he was not picked as the Crown Prince. He still holds ambitions of becoming the King one day.
Jin is Kim Min Jae’s son and the King’s son-in-law. Due to his position as the King’s son-in-law, he is unable to take part in politics and only seeks out pleasure.

Both are historicals where w woman pretends to be a man. There are many historicals where a woman pretends to be a man, but what makes this two shows similar is that the woman started to pretend to be a man after her brother's death (and she takes identity of her brother).

While completely different in tone (MUD is light and funny, TKA is much darker and heavier) both begin with the king killing the midwives to hide a birth secret and the FL being raised as a male crown prince.

*In both dramas, there is a power difference between the ML and the FL. *

MAIN PLOT:
-In The Red Sleeve there is love between crown prince (ML) and a court maid (FL).
-In The King's Affection it's the opposite. The FL is disguised as a man and she is also the crown prince who is loved by the royal tutor, who is our ML.

SIMILAR TOPICS OF:
-Childhood nostalgia
-Difficult and abusive family relationships
-Political drama
-Injustice in Joseon; class problems and gender inequality
-Love between people from different classes.
-Multidimensional characters with their own ambitions.
(All of these topics affect the relationship of the FL and ML. )

DIFFERENCES BETWEEN DRAMAS:
-The ML in the Red Sleeve is way more toxic, and the FL is more often helpless despite her clever ways. It can be fun to watch toxic couples, it is like a guilty pleasure but this couple was unusually toxic, in my opinion.
-The King's Affection has a bit more humor. The FL is quite amusing as the 'cold ice prince' while the ML tries to assist her. His love is more pure.
-Overall, The Red Sleeve is more sad and tragic because the FL suffers a lot and she is way more helpless. The FL only wants to be able to make her own decisions. It's realistic, I guess... But it made me cry more and not laugh as much as in The King's Affection, despite this series having a few slow episodes in the beginning.

If you like one of these, chances are that you'll like the other one.

About a twins boy & girl who was born in a kingdom but having twins is a big taboo so they decide to throw away the girl in The King's Affection but in The Emperor Owner of the Mask is about a King who switching place with a poor guy & wear a mask to hide that he had a scar in his face. Both drama is my favorite saeguk/period traditional drama & must watch dramas.

A story about the king who is actually a woman in disguise. It's one of the most well-played gender-bender I've ever seen. Despite her obvious feminine features, she plays the role so well that I forget that she's female. And their love story is immaculate, and he also falls for her while still thinking she is a guy and fully prepares to risk it all for his love for "him".

i recommend becoz it really have similar plot ^-^'' in both dramas the queen has twins and they seperate dissimilarities is mirror of witch is fantasy dark magic related

It tells both the heart-fluttering love story and fierce obsession of a King with two opposite personalities and an assassin girl who wants to kill him but ends up falling in love with him.

Crown Prince Sajo Hyun is an intellectual character who uses his innate artistic sense to work as a fashion designer at a downtown boutique while hiding his identity of crown prince. He has a wound deep down in his heart from his childhood due to his oppressive father Sajo Seung. Sajo Hyun’s other personality Ak Hee is a charming character who can easily seduce others, but he is cursed to feel extreme pain when he makes physical touch with others.

Yeon Wol lives a life full of twists and turns, going from an assassin to concubine. Yeon Wol is the royal descendant of the fallen Yeon Dynasty and the only daughter of Yeon Poong Hak. Yeon Wol hides her identity and becomes assassin Gye Ra to avenge her family. While trying to assassinate the king, she falls into a trap set by an unknown person and wakes up the next day with no memory of her past.

Both these dramas have a lot of similarities. Basically, they are both sad historical /romantic drama from the Joseon era.

Star crossed lovers who cannot be together due to reasons beyond their control. The kings secretly plot to disrupt the plans of crafty prime ministers who have exalted them to their royal positions and who hold all the de facto power.

The guy feels gay when they loved withvthe same gender without them knowing that they loved is truly a girl. I like how the girl hides their true identity .
