Trap (2019)

Kill It airs in the same time slot as Trap, and it might be part of OCN’s “Dramatic Cinema” project. they are both fast paced and action packed...

But have that "I'm being setup" setup, and both have MLs in deep mess trying to clean their names
Both are full of tension and good crime pace

they both have that movie like quality, they both have Choi Byung Mo, and a dark vibe that walks on the gray line of what's good and what's bad

Both leads are desperately trying to save their loved ones. Also, both are filled with suspense and mystery. Both are from OCN.

Reputable anchorman seeking justice for personal reasons and are able to convince the public that their intentions are sincere, noble and worthy.

A drama with layers of intrigue, twist and conspiracies where the truth seekers efforts are constantly being blocked or thwarted by the evil enemy and their own.

Both dramas give off the same eerie and sinister atmosphere. Both take place in a more rural area where something happens that forces the leads to confront their family/past. And in both dramas that is connected to the course. Both give off a very similar vibe.

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 shows pit the ML against a cult:
>> In SM2 the ML is an ex-con who is trying to save/help his townsmen from a religious group who are really aiming to take away their money.
>> In Trap, both the ML (detective) and the FL (criminal profiler) discover and try to take down a cult/group of serial killers.

Both dramas revolve around a man in a rural area getting involved in a murder mysteries that reconnects him with his past. Both do questionable actions, while also teaming up with a detective to solve the case. Both dramas give off the same eery and sinister feeling.

Both have an eerie and sinister atmosphere. Both stories are revealed to be much more than what they initially seem to be and have a layered narrative, shifting between the past and the present.
