Hitman (2020)

Hitman: Agent Jun similar and Okay! Madam have a few things in common:

1. Both have characters with a secret past that puts their family in danger.
2. Both characters are badass.
3. Both are action packed comedies.

- ML is Spy/Agent
-FL is the "boss" (between the two leads)
- His family does not know his identity
- In general, they gave me the same vibe!

Both are action-comedies where the main characters were skilled agents in the past and now have a new identity.

It's the same type of premise, a retired hitman, partially in this case.
The fights are great.
There's also a sequel.

Both Action Comedy with male lead skilled in martial arts and fight against many then win, also both are very funny. The same level of quality.

similar comedy vibe, both used some decent action scenes
the chemistry between the leads top notch

Both have similar comedic value

Both have kidnapping involved, The mains try to retrieve the kidnapped.

Both have bromance

Both are Action packed

Both feature hitmen who write online novels or draws webtoons about their real experiences as hitmen under the guise of fiction, which leads to chaos and their lives changing forever.

LTNS is more about romance and action while H:AJ is more of an action comedy but they both have similar backbone stories of the hitman wanting to leave his life as a killer to start a life with his new family.

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