Ghost Doctor (2022)

In addition to Rain being in both and having pretty contrasting personalities to portray, both shows are bromance-intense supernatural comedies, focus on character growth/redemption, and involve second chances.

The supernatural experience in the medical field is present in both creations and the idea of crime and the supernatural helping to solve the conflicts surrounding the hospital's administration or higher ups.

Both dramas have ghost main characters
Both dramas solve the ghost problems to go away and move on
Both dramas have funny scenes

1) Both are medical dramas
2) Both MLs develop a strong mentor-cum-friend-ship
3) Both have scenes of saving patients on the street

The Last Breakthrough is a hidden not-to-missed gem on docs without borders, on saving lives in resource strikened areas, and helping patients beyond treating them.

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

Both have two main leads doctors
Both have friendship brotherhood relationship
Both have medical cases that discuss morals and ethics

When I saw the circle ring in the eyes, it remind me of the male lead in the Japaneses movie called Impossibility defense. Both has supernatural power for good and for bad.

Both male lead were dead or near dead, but the soul still wonder around
The story tells how the male lead spirit trying to fix things, he see things more clear, and understand .
Can he get things straighten out? Or is he helpless?

both about two people living in a same body and the bromance is uncanny
both the male leads are self centred and think only about themselves

Kim Bum in both films.
Both film the male lead has supernatural power.
Their eyes turned ghost like ring/circle
Will see what else Ghost Story bring us

Both are time travel with two male main lead
They can be antagonist or protagonist
Both are fun, mystery, action, drama
One younger and one older inter-twisted.

Both drama involved two generation spirit intertwined.
They somehow able to get into others body and the body act for the other person
It shows some contrast of younger generation silly, careless, and free characters with the older generation serious, thoughtful, and reserved character.
Some fun, funny, crazy, serious, and confusing moments.

The male lead was able to travel back and forth to get things fix.
He have had some regret, unfinished business in previous life
Can he get things done? Can he achieved his wish? Can others help his spirit in any other way?

Both is about two men in which one is a ghost while the other is human .But this is medical drama and a bit more serious but still very funny not a bl kinda thing but has some good bromance

ML can see ghosts and makes relationships with the ghosts. In Showtime, ML has a give and take relationship with the ghosts while in Ghost Doc, ML is really only giving help to the ghosts.
