Mask (2015)

Kinda similar doppelgänger revenge stories. Mask is a Korean drama, set in the modern Korean upper class. The poor FL has to replace her doppelgänger after the doppelgänger was murdered. The double is a Chinese drama. The FL takes the identity of her friend after the friend dies. The FL takes revenge on the people that tried to murder her.

Both main leads are suffering from financial crisis. Both of them found their doppelganger unfortunately dead. Both main leads pretend to be that rich doppelganger just to escape poverty and enjoy comfort of life.

Both have a male lead, obsessed with cleanliness and with other PTSD and OCD problems displayed. He is a CEO, so he has to keep his troubles a secret. Is rich, but mistreated by his own family (which is the root of all of his psychological problems).
Female lead is poor, clumsy. Has problems hiding her own feeling as they are always being easily read on her face. He is business-smart.. she is innocent.

Yoshino Michi is 32 years old. She's been married for five years, but hasn't had sex for the last two. It's not as if she doesn't get along with her husband, it's just that the sex part is lacking. It was a bit unexpected, but one night when she when drinking with her colleague, Niina Makoto, she wound up confessing that her marriage had turned sexless. And then, a shocked Niina responded "My marriage is sexless, too," and smiled with a lonely look in his eyes.

They both have dobbelgangers in the drama
there is one rich girl and one poor girl that look alike, the rich girl disappears and the poor girl that looks like her takes her place

Both have girls who look the same and when the rich girl disappears, the poor girl has to take her place. Also the poor girl pretends to be the rich girl too.

Both have one of the leads impersonating either someone with the same name or someone who looks just like them. In the process, they fall in love with the people that they have to dupe.

Different plots on the whole, but I feel like both sort of tell the story of a person that was backed into a corner and how she tries to fight her way out. Also, both dramas deal with both very evil characters and those with shades of gray. Both are on the darker side (AM is Def darkerr) with specks of humor. Finally, both have story that really sucks you in.

Similar infidelity plot both ML & FL attract to each other. Both fall in love eventhough so many obstacles in front of them. Can they overcome it? This genre very interesting & is a must watch drama.

Both dramas carry strong female leads that have to do many things to survive within their environments. The osts and filming are very similar and beautiful. They both have a darker mood and include similar themes such as betrayal, cheating, tragedy, and a lot of suspension. Would highly recommend if you enjoyed Misty.

Despite the name "Five Fingers" its actually really good. It's also a drama about revenge. It also has the same lead. The main lead plays a sort of instrument in both dramas.

A popular teenager inexplicably finds herself in the body of an unpopular classmate - and her body's new owner has no intention of switching back. The series centers on Ayumi Kohinata, a first-year high school student who has a cute and shy personality. She's excited that she just started dating her first boyfriend, but on the day of their first date, she gets a mysterious call from her classmate Zenko Umine. Zenko says she's going to die, and Ayumi witnesses Zenko jumping from a building. The next thing she knows, Ayumi wakes up in a hospital, but in Zenko's body.

A woman has to deceive man. In the beginning she is controlled by someone else. However, at a certain point she will follow her own agenda and develope feelings for her target.

Both dramas deals with shaming and plotting of rich family members against each others and a ordinary woman who gets drawn into this world.

Both FL take the identity of an other person.
Both FL were poor and their new identity made them rich.

Both are melodramas about a woman who lies everyone and conceals her own identity for her own good. Both women have different reasons and situations but the overall feel is similar.
