Ancient Detective (2020)

Both drama are definitely original, kept in a similar climate when it comes to action, costumes, combat scenes and storytelling. They are not kept in the same universe and are not twin, they simply have an interesting style of filming that combines the world of ancient China with aesthetics close to the viewer in the 21st century. If you liked one, you'll love the other too.

Awesome wuxia
Nicely paced suspense plot progression -- Both follow a series of smaller mysteries/arcs that build upon one another until the overarching mystery is solved.
Physically weak but mentally strong ML protected by butt-kicking friends/FL.
Some bromance

Both are similar but are in different time periods.
-find out who the killer is
-have great profiling skills
-ml have different characters

Both MLs are weak and on a quest, FLs are strong (brains & brawn sort of relationship). Both dramas have pretty aesthetics.

Both dramas are about investigations in historical times \

both drama has good friendship between male leads

Both are wuxias with beautiful aesthetics. The FLs are strong and the MLs are suffering from a cold poison.

Ancient detective is a Chinese drama but it's too similar to this one ,, Both have cases in Historical time to investigate ,, Both have good Bromance between the intelligent royal or high class detective and his friend who is lesser than him ignorant and more of a subordinate to him
Both dramas have lots of comedic scenes and good laughs
Both dramas have slight Romantic stories not the main focus but the Brotherhood or the friendship is clearer in them both

Zhang Jing Yi is the FL in both. The chemistry is natural. The relationship had depth. However, BEITD does not have a satisfactory ending.

Both drama deals with friendship and solving mysteries. There is some bromance while the cp takes a back burner to the overall plot.

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 dramas are low budget web drama, but very well made. Though different storylines, both bring you to the end of the story wanting more! (praying for a SEASON 2!!!)
