W

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

ML in Shopping King Louie is rich (but loses his memory)

Both are light fluffy romcoms with lots of cute moments

ML in Shopping King Louie becomes much nicer and adorably cute (and a bit stupid) after he loses his memory but is the brooding type before then.

In both dramas, the FL enters a fictional world. In “The First Night with the Duke” the FL enters a romance manhwa while in “W” the FL enters an action manhwa. In both, the appearance of the FL significantly changes the plot line, and their involvement in the story turns the FLs into main characters of their respective worlds. Both dramas have a bit of action, romance, and comedy— so I highly recommend them if you’re looking for a good show to watch!!

Takashiro Naoya is a handsome salaryman who works for a top company. However, he is also a notorious playboy with a bad taste in women. By chance, he ends up becoming the live-in muse for Fukunaga Akane, an erotic fiction writer who has little experience in love.

Both are full of suspense, thriller and sweet romance... The main leads are really good for both the drama..

A female outsider enters a parallel world by mistake (or not so in MP) and tries to implement her absolute rights as one of the creators of this world in order to change the end result.

They both about crosswords travellers, thriller , romance ,unpredictable ,entertaining to watch and well executed plot . Give it a chance .you’ll love it .

Both delve into the psyche of killers and psychopaths. Both are crime solving dramas and relatively fast-paced.

They are both fantasy guys (one from a comic book and then the other from a stand up pop up cardboard advertisement) and they made an appearance on the FL's life and fell in love...

Both dramas are circled around an airhead and doctor main heroine and a rich-boy male lead. The marriage aspect seems a bit similar as well.
