Hen Jun Bu Si Jiang Lou Yue (2021)

Police officer Pang Hong Mei amid the many obstacles created by U.S. and Jiang spy agents, rescued Ji Danyang, a patriotic scientist who returned from the United States from the enemy spy. She accompanied Ji Danyang to Lumen City to participate in the "Water Drop Project". Enemy special forces formulated a sabotage plan codenamed "Operation Rock" and concentrated their forces and tried to destroy the "Water Drop Project." Pang Hongmei and Ji Dan Yang fought a life-and-death battle with enemy agents in Lumen, thwarted the enemy's conspiracy, protected the "Water Drop Project" and finally achieved the expected success. The couple who went through the test of life and death, also realized their dreams and firm ideals.

Both dramas are set in the Chinese Republican Era. While Detective L has comedy, Killer and Healer is more serious themed and has a censored romance between two male leads.

Both drama have Strong Bromance story
Both dramas have the same main lead actor
Both are from the same shitty channel Mango who doesn't care about it's dramas

Both dramas have Two friends who fought gangsters and police corruption
they tried to protect and save each other from the cases they are involved in
The korean drama has more fight scenes and side romantic story
not sure about the chinese one yet

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide

Both are bromance/Bl themed dramas with one of the lead character being a cop and the other a doctor.

Both are kind of similar. ..both includes police investigation theme, crime solving duo, perfect chemistry between both male leads and we can see bromance in both drama....

The main leads are polar opposites. Both main leads in "Killer and Healer" and "The Sign" have opposite personalities that complement each other well.

Both republican era dramas
Both have struggles in desperate times
Both are fighting to protect their country and keeping it safe in chaos and war
killing people is the most common theme and it shows How turbulent time it was

Both have crime, action and two male leads and no female lead.
Both guys in under the skin are detectives.
Both guys are there for one another in under the skin too.
Not a lot of bromance in under the skin as compared to Killer and healer but still, good enough and the plot is good too.

-both friendship
-both brotherhood
-both produce from china mainland
-both rating above 8.4(from my view,if rating above 8.0 usually the drama is recommend to watch,my bench mark for drama is 8.5 and above) but sometime drama is good but rating so low.
-both do not have romance
-the spirealm is about play game
-killer and healer is about police and doctor

why you must watching killer and healer
-sound track so beautiful like the untamed,very emotional
-chemistry between main lead the best

similar bromance story with great chemistry between the two male leads
also both in republican era<<<<

Both Bromance dramas based on Brotherhood and caring for each other but Killer and healer is more eccentric than I don't want to be brothers with you
