The main leads on both movie were dead but spirit wonder around. Able to see everything but others couldn’t see him. Both has a beautiful lover, but had to let go of her ….

Both has a main lead that can see ghost. They refused to help at first, the supernatural power that they have would put in a good use at the end

Both movies main leads are dead and second main lead was able to help the first main lead to fulfill his unfinished business. One about crime, the other has music genre, touch of romance

The death has unsettle business, souls still hanging around attempting to finish the mission. One is comedy the other one is love family suiting story. One has bromance the other one is romantic

The young police on one movie remind me of the other movie, perhaps it is the uniform. Both movies show the young policeman trying to crack the crime, facing fierce dangerous challenges. Lots of humors

Only certain people can see ghost or dead soul. Both Korean movie/drama has a main lead can see dead soul wondering around.

one of the biggest reasons is Zan Xiao. and the mystery of the character of ML.
both are amazing. also full of unconditional love with sense.

Both are fantasy dramas with a similar feel and tone, with a long past connection between the leads. Both MLs are very devoted to the FL.

ML vs. FL is a supernatural being who is collecting something (scents vs. emotions) from humans. They end up falling in love with the human who has the last thing they need and must make a difficult decision.

both execute how money can change people and include murders. both have makjang elements and have the same actor uhm ki joon.
