Both are about former classmates where one offers the other to become roommates to focus better on their job. While the rent for the room is basically "Just do whatever I tell you" which might be house work or might be something else :)

- Noona/Jiejie romance (older woman/younger man) but the age gap isn't too big (couple of years estimated)
- CEO FL
- Bold, assertive, mature, and dominant FLs
- Sweet, innocent, and submissive MLs
- Both are very steamy with good chemistry
- Gender Role Reversal vibes in both (+ softcore femdom)
- Both start off with the leads meeting in a bar and hooking up

Both dramas involve the ML being asked to pose as his twin brother. In Fervent Kiss, its by his uncle, and the FL takes time to figure it out, whereas in Be Your Knight, the FL drags the ML into the story and the rest of their family, mainly their aunt, figures it out over time.
The rest of the dramas have different vibes, one in modern setting, the other in a more dangerous republican era setting.

Fluffy first love, cute happy female leads when they were younger.. both dramas leave a lingering sweet feeling for a long time

- CEO FL
- Merman ML
- Cold FL x Warm ML
- ML is innocent and cute
- ML ends up working under FL as her secretary/assistant
- Cohabitation

FL acts like she is mentally impaired to get revenge of her family (that attempted to kill her to get her company)

Mindless action, death and gore.
Roundup- blades fights, death, ganster, hand to hand combat, no guns. fun and funny
Time to Hunt- hunting, gun fight, dystopian, gore, nest level thrill and cinematography. Thrill

Lee Sin is a university student majoring in modern music. He is the vocalist of the band "The Stupid" and also plays the guitar. He is known for his good looks and his strong passion for music but is, in reality, a cold person who is uninterested in non-music-related things and has no dreams or plans for the future. Sin initially likes a dance professor at his university, but this all changes when he meets Lee Gyu Won.

Lee Gyu Won is a bright and outgoing student who was born into a prestigious family and is majoring in traditional Korean instruments, especially the gayageum. Gyu Won's grandfather, Lee Dong Gun, is one of the top 3 traditional musicians of his age, and his biggest wish is to have his granddaughter trained to become a traditional music prodigy in 10 years' time. Trying to live up to her grandfather's expectations, Gyu Won immerses herself in training and becomes a university student who knows nothing besides traditional music. As Gyu Won's friends are fans of "The Stupid", she was forced to go to the band's concert with them. There, she sees Lee Sin performing live and is immediately captivated by him

A love story about a depressed genius music composer Kang Han Gyeol who meets the high school student Yoon So Rim when he’s living under a hidden identity. With her courageous honesty and beautiful singing, So Rim draws Han Gyeol back to her again and again. They meet love obstacles along the way as So Rim finds out that Han Gyeol was actually Crude Play's producer K.

Male leads have similar character arcs and elements of fantasy are similar.

The fl is cisgender who join drag to solve her sisters murder, and then meet the ml who is also detective undercover as a drag queen.

Both shows are centred on romance in the workplace with the same ML. However, Touch Your Heart focuses a lot more on comedy. I also prefer Touch Your Heart in terms of the second couples and plot. If you enjoyed The Divorce Insurance, you will definitely enjoy Touch Your Heart.
