Same action fast paced and the female leads are similar in several aspects. Both male leads assume the identity of another person. Both of them have to work to some bad guy to achieve their goal.

And at least, they deal with corruption in high places with a touch of comedy.

protagonists who end up being involved in cases of corrupt politicians and start to investigate because of someone important to them who was killed.

-both have agile and skillful protagonists

These two dramas are similar when it comes to the main leads being wrongfully accused of deeds they didn't commit yet took the blame/fall for. How one wrong accusation ruined their life. Finding out the truth over that event is also a similar theme in both drama.

Both dramas have the premise of someone going ‘undercover’ to solve an old case, and with false identities involved. In You’re all Surrounded it’s more planned to happen while in Doubtful Victory it’s more by accident, but both MCs are personally involved in the old case and solving it is/becomes their goal.

Both dramas also have a female lead that knows the male lead from when they were children, and suspects his identity. There’s more romance in You’re all Surrounded, though.
