W (2016)

I don't know why but for me they seemed similar, I think it was the "supernatural/fantasy" aspect, if you liked Abyss I'm sure you'll like W too.

Female lead travels inside a fictional world in both dramas and find love.While world in W is set in the comic book, Unique lady goes inside a game world.

Both female leads look alike and are strong and decidide,the 2 dramas are about parallel universes and they are really good romantic stories .

Both dramas have crossworlds travel between the world of an action novel/manga with a suffering protagonist fated to be killed, and the real world of the writer.

They have a very similar feel. Both are dramas with unpredictable stories, dark plot, mysterious antagonists and plot twists.

In both the ML (played by Lee Jong Suk) is falsely accused of a crime that he didn't do and he tries to prove his innocence by exposing the real villain.

Both of the stories are really unpredictable. W and Liar Game (Korean Remake) Keep you hanging, although W has 16 episodes and Liar game has 12 episodes.. which is really sad because I wished it was longer...

Ambos envolvem sonhos/outro mundo. Achei incrível a temática e achei similar principalmente pelos desenhos e todas os momentos envolvendo webtoon

both has manga/webtoon which is drawn and kinda comes to life
in the movie it comes true for real in the real life
in W kdrama it first builts the other world where characters appear are developed and slowly from there it begins to actually affect reality

Both about two differents worlds and the female lead moving from her world to another. FL meeting someone who helps her in need and there is a secret about the 2 worlds that the leads are working to solve.

W contains romance, while Derailment is still ongoing drama so I don`t know yet if it has any romance at all.

both have a male lead who is not a real human
both have a lot of suspense
both have a love story that people do not approve of

Both female leads are doctors with similar personality types. They both get transported to another realm/time period. While Faith is more of a medical drama and sageuk, W is more of a modern day romantic comedy.

Both have male protagonists that were framed for their family murders and were unjustly imprisoned. They both struggle to bring the truth to light.

Both involve travelling to a different world, changing the story in that alternative world and falling in love with one of the characters there.

Both have handsome male lead characters & involve action in the form of traveling into literature. Both jump in and out of comic/ books as they learn how to solve/navigate worlds along with elements of fantasy themes.

Both are about webtoons

W is about the FL going into the webtoon and then meeting the ML whilst True Beauty is a webtoon itself.

Both have bright cinematography and are fairly light romcoms

Both involve MLs that are quite stoic at first
