Two Cops (2017)

Both dramas have the body-swap/body possession supernatural concept. The characters try to approach people around their original lives, but as they are in another body, those people don't recognise them and they get ridiculed for being weird or having mental problems.

Both dramas have the body-swap/body possession concept.
The original character found a clue that lead them to solve the mystery/case but before they were able to reveal it, they had an accident which caused them to die/their body to be possessed by someone else. The characters that possess the body aim to use their new identity as a detective to get away with certain things such as handling a gun, or accessing police data.

Both dramas are about ghosts and funny ghost stories
both dramas deal with ghost cases and resolve them

A Ghost and a detective investigate a murder case that has a connection to them both.
The Ghost Detective focuses more on the ghost world while Two Cops leaves it a mystery.
Even though The Ghost Detective seems a bit darker both dramas have comedy.
Both have a little of ghost romance as well :)

Both are based on finding out about the corruption within the police force which was interesting. Local Hero focused more on spying and secret agents whereas Two Cops blends the use of conmans and cops working together to achieve a greater goal.

Both have as a subplot a case of an accident that might be responsible for the death of one of the protagonist's parents death and involves a corrupt make polition and his son.

A detective in coma possesses the other detective's body in two cops similar to ghost doctor I guess

Both FL are reporter
Both ML are in the law inforcement (one a prosecutor the other a cop)
The main character are related due to an accident that happened in childhood
There is a love triangle with a nice 2nd lead that isn't toxic.
Supernatural element (One ghost and possession the other seeing the future)
Both have nice romance but it isn't the main plot.
Both have a sort of bromance.
Overall they have a similar vibe while being their own style.

After watching The Dude In Me, I was instantly reminded of Two Cops. Both The Dude in me and Two Cops revolve around body switching. One of the leads in both the movie and the drama is a gangstger. Both combine action and romantic elements, I also found both humorous and easy to watch. The character developments of the movie and the show are interresting and I think both plots are enjoyable.

- Body switching
- Action, romance, humor

The ML of Goodbye Again has stated that he referenced "Two Cops" in preparation for the spirit possession his role called for.

- Both are police investigation/crime dramas with comedy
- Both have Kim sun ho
- Great bromance

Both dramas stars Lee Hyeri as the female lead. Both Jian and Roseo lost their fathers when they were younger due to some secret that led to their fathers being killed. Both of Jian and Roseo's love interest were cops; Dongtak is a detective in the violent crimes unit while Young is an inspector in Saheonbu. Both Dongtak and Young were indirectly responsible to the death of Jian and Roseo's father. In both stories, our main pair end up working together to unravel the truth at the risk of their own lives.

- Same male lead.
- In Two Cops male lead goes through a change of spirit; in Oh My Ghostess the female
lead's spirit keeps changing.
- The spirit needs to solve a murder case.

Bothe dramas have one cop acting with a ghost in his head only or another personality acting on his behalf
both are packed with action thriller and funny scenes

Both dramas are based off of a mystery that happened in the past but significantly affects the characters in the present. Both have passionate cops who must partner with another to solve a murder mystery. Although two cops is more of a comedy, in both dramas there is a character who must come to terms with a fantastical/unbelievable situation. Lost spirit vs time travelling walkie-talkie signal.
