Impossibility Defense (2018)

It both talks about somebody with a special ability that eventually found somebody "immune" to it which caused the "villain" to do everything to harm the person immune to his abilities.

A mysterious person that takes up the murderous requests of people. In both drama these people accept a bargain, while in Jigoku Shoujo its their soul that ends up in hell, in Imposibility Defense its death if their request is not pure.

Both have the feeling of hypnosis.
Great male lead.
Deep acting, your eyes couldn’t get off the face.
Psychology and mystery on both.

Both are psychology mystery
Both main lead will suck you in to their face, good acting
There are good and bad side of their act

The main lead has hidden theory, agenda, skillful, thoughtful, kind inside. This is the stories that make you think, kind of loving the bad guys

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.

A mystical person appears in order to bring out the dark side of human beings. The motivation is not totally clear, but both main characters seem to enjoy the suffering they create.

Both make lead has supernatural power
Both has the eyes bright up ring like when they use their special power
They are not necessary bad, they use power for good.

One using the supernatural power for good. Combination of evil and good. Hate, greed and jealousy bring out the pathetic side of a person. Self awareness.

Both main lead inherited supernatural power. Both are honest. One is dark Japanese movie the other one is funny Korean drama

When I read eyes color change, immediately I remember this Japanese movie.
The eye color changed indicate some supernatural power is going to happen

Both are good Japanese movies to watch.
Mystery, murder, action, psychology, thriller
Love both main male lead.

The hitman has a good side of it when he or they perform a job. All the people that hire the hitman has to pay for their motive

Both young man has the supernatural power. Both has that eyes that change colors and like a ring. They use their power to do good instead

This is the movie that is from my understanding, the next part of the story. Some parts from the drama are mentioned in the movie.
