In both dramas a lady sees scary spirits/ghosts and feels exhausted and miserable because of it. People around her think she is cursed/crazy (both of them have a weird smile XD). Then she finds a man with special energy that can help her with a touch (such as holding hands, since it passes the energy).
Both teams have "good criminals" that use their skills of fraud and deception in order to stop some bad guys and criminal organizations.
Both are teams solving crimes that the police couldn't. They use extraordinary and sometimes illegal methods.
In the first part of Last One Standing there is a similar scenario with people becoming "zombies" because of a disease. There is even a similar character of husband trying to help his wife who [SPOILER] became a zombie.
I felt like Chen Yun Ru's character is similar to Umine Zenko's one , since both initially feel unloved and disconnected from society. Both dramas talk about "being inside" someone else's body.
In both the protagonist works as police officer and suffers from discrimination, because his father is convicted for murder.
Both talk about mysterious characters and about......................................................................SPOILER. human cloning.
Both dramas talk about moral dilemmas surrounding human cloning and have a quite dark atmosphere. The relationships of the characters are complicated and in some cases obsessive.
In both dramas the protagonists fates are linked the way that then something good happens to one, something bad must happen to the other.
In both one of the protagonists have a supernatural power to predict people's death in their dreams.
Both are stories of revenge with competition of two restaurants: one already very famous and influent, but with problems caused by CEO's incompetent and spoiled son; the other new that is a mixture of passion, talent and newbies who don't have anything to do with cuisine, but who learned a lot and became very skilled. In both the protagonists have big age gap.
They take place in the same universe - The Great Thousand World . The protagonists know each other in the original story (web-novel and video game).
