Knight Flower

Yoshida, the diligent class representative, couldn't help but feel a growing sense of concern for her classmate, Yano; day after day, he would arrive at school covered in injuries, leaving her puzzled and worried about the cause.

Determined to get to the bottom of the mystery, Yoshida and her friends decided to investigate Yano's situation more closely, discovering that Yano is an extremely unlucky boy! What's more, he's unable to lead a normal high school life due to his 'unlucky constitution.' Moved by Yano's plight, Yoshida resolved to provide him with unwavering support.

As she spent more time with Yano, she found herself increasingly drawn to his pure and straightforward nature, but the distance between them just didn't seem too close.

Meanwhile, Yoshida is confessed to by the most popular boy in school... This unexpected turn of events only further complicates the already delicate situation as Yano, touched by Yoshida's kindness, begins to develop feelings for her.

Both dramas have strong and tomboyish female main characters who lived under strong confucianism tradition that limits their freedom. Both of their characters are very ahead of their time. The difference is that the FL in Mr. Queen is actually a modern male soul trapped in FL's body

Both dramas are presenting harsh reality that are faced by women in the pasts. Like in Knight Flower, woman must dedicate her life to her husband even after his death. In Aema, woman may have career on her own but she must face male's domination, in this case like CEO Koo who is so exploitative toward his actresses

All the gods will be leaving before the last rain of doomsday. However, an ordinary human girl unexpectedly puts a dent in their plans to retreat thus causing the world to move towards the unknown. Based on the animistic mythology of the Amis tribe, the gods are no longer willing to bless the land that is plagued with environmental issues. One by one, the gods depart the world they once loved. A human girl discovers that the opportunity to reverse her destiny lies within herself and her guardian. Before the final day of judgment, a love story between human and god unfolds.

Both have strong lead. The female lead has no dependency on her counterpart.
It is a period piece. And the darkest secret is yet to reveal...

Different genre, but for me these two have some similarities when it comes to the vibe they give.
As I wrote in my review for My Sweet Mobster, it is kind of like the scriptwriters didn't take themselves too seriously, which resulted in some lighthearted humor.
Both of these shows also showcases underlying issues; for MSM it is ex-convicts' struggles to get back into society, and for KF it is widows' status during Joseon times.

Both dramas tackles issue about yeolnyeo/virtuous lady during joseon era. Both female leads lost their husbands at their marriage day and expectation of both ladies to be loyal to their deceased husband

Comedic film of a fusion-historical genre. Cute lover boy Heo Saek becomes Joseon's first male gisaeng and a flower-like woman named Hae Won who thinks ahead of her time, search for true love together.

In 1867, Sin Jae Hyo leads the Dongrijungsa, which teaches pansori (traditional Korean musical storytelling). A young girl, Chae Seon, who wants to perform pansori, appears in front of him. Chae Seon has dreamed of performing pansori since she first heard Sin Jae Hyo perform when she was little, but Sin Jae Hyo turns her down because women are not allowed to perform pansori. Chae Seon then disguises herself as a man and enters the Dongrijungsa to learn pansori, but Sin Jae Hyo doesn’t accept her as his student. One day, he hears Daewongun, the most powerful man in Joseon and the father of the King, is going to hold a national competition of pansori performers known as “Naksungyeon”. Sin Jae Hyo decides to teach Chae Seon, who has a true voice to perform “Chunhyangga". If anyone finds out that Chae Seon is a woman, Sin Jae Hyo and Chae Seon will both face death.

In the episode 9 of the Fiery Priest season 2. Father Michael and Prosecutor Angela disguise, and the one who cosplay by Prosecutor Angela is her character in The Knight Flower. This story was focus on Lee Hanee but this character was shown in the episode 9 of the season 2 and it's kinda cool to see her again wearing her clothes as Yeohwah.

- Plot is different but gives the same vibes
- Double Life ML/FL
- Daytime they lead a normal life but at night they save people who needs help

- Plot is different but gives the same vibes
- Double Life ML/FL
- Both dramas are in Joseon Era
- Daytime they lead a normal life but at night they save people who needs help
- only difference is that Iljimae is like Robin Hood were he steals from corrupt people

Another noona romance where Noona needs no saving. Black humor abounds as well. Mystery plot in both.

Also know as The Memorial Gate for Virtuous Women (???) is a 1962 South Korean film directed by Shin Sang-ok that gives a close up look at the reality of being a widow in Joseon.

The film tells the story of the widow of a nobleman who bears a son after having an affair with her servant. The servant and the baby are driven from the home by the woman's irate in-laws.

Similarities: comedy, past connections, good chemistry, a good story, great supporting characters
