I've Fallen for You (2020)

FL likes to do detective work as a hobby, and finds work with the magistrate ML, solving criminal cases. Both are also fluffy dramas.

Both dramas are a blend of mystery and romance with a initially brash-seeming inwardly marshmallow of a ML and a innocent FL.

The female lead has the same job or talent, haven't seen it but gives the same vibe, I don't think she is that quirky here but it looks fun as well.

Both are upbeat mystery/romance dramas with a sweet couple.

If you thought that "I've fallen for you" is lacking martial arts and intense mystery and thought-process, then check out "Young Blood"!!
I guarantee 150% that this drama will not fail you!! ???

Both have a cutesy FL and stoic ML. Both are mystery/investigation dramas.
..............................................

They have the following similarities:
Forced marriage
Carefree son of a rich family
Bride from a low status family
Smart Female Lead
Spoiled Rich Male Lead

The plot of I've Fallen for you with regards to the relationship progress of the couple is also quite similar at the start. They got married due to the male lead family's bidding. The wife was technically kidnapped, but she ended being treated well in the male lead's household. The husband's parents are also very doting on their new daughter in law. The female lead is skilled in a certain field. She also contributes to the male lead's transformation from being the city's spoiled rich kid, to becoming a great man.

Chef Fang and I've Fallen For You have some similarities:
* a nice girl falls deeply in love with a roguish guy, she wins the hearts of her in-laws and later of her husband;
* the bridegroom changes for the better because of his marriage
* both have a leading character with a royal origin
* the marriage of the ML and FL isn't consumed
* the ML and FL solve mysteries together
The difference is
* In Chef Fang the girl is from noble birth, in I've Fallen For You it is the boy
* One girl is accomplished in cooking, the other in forensic research

I've Fallen For You is similar to Under The Power:
* there's a character with unknown royal origin
* a secret in the past that binds the ML and FL together
* the FL works for the police, she's doing forensic research
* the ML isn't impressed by the FL in the beginning

The differences:
* Under The Power has a slow burn romance, I've Fallen For You has romance right in the early years of the leading couple
* Under The Power is much darker with a real bad ass antagonist
* The father in Under The Power has done some shameful things, the father in I've Fallen For You is honest and supportive

I've Fallen For You and Dr. Cutie have similarities:
* the FL is more cute than pretty
* the FL falls first in love, later on the ML follows
* the FL hides her identity
* the ML and FL have childhood memories in which they play a role themselves without knowing this
The differences:
* Dr Cutie is a story of revenge, I've Fallen For You is a story of finding a lost love
* The girl in Dr Cutie disguises as a man, in I've Fallen For You she takes the identity of another bride
* In Dr Cutie two brothers are vying for the love of the FL, in I've Fallen For You it's a male harem

Ancient Detective focuses more on crime solving compared to I've Fallen For You. It also has a bit of mild romance in it.

Both are exaggerated comedies set in a historical period. The characters are all quirky and lovable with great chemistry.
