Oh My Drama Lover (2020)

-Both get transferred to alternate novel universe.
-Both female leads are given antagonistic position in the novel.
-Both struggle to be positive characters and impress the male lead.
-Both the male and female leads meet again in the real world.

In both dramas, the female lead traverses into a story world that she wrote and finds that she is actually the "evil" second female lead. However, "Oh My Drama Lover" is different in that the female lead loses her memory and her appearance is different in the story world. Furthermore, the actual male lead of the drama is not the story's written male lead.

There are times when the female lead finds herself being unable to control her actions, which is similar to the "stages" in EY. However, only she is affected by these "stages". Similarly, the actual male lead ends up being different from the original written male lead.

Similar vibes but in Og My Drama Lover FL is a character in her own written story whereas Meet by Window FL is a character in someone else's story (and able to come and go)

its quite similar....
Here, FL actually time travels back and meet ML.
FL and ML meets in the real world.

The 2 Doramas share fantasy , fate , romance ,suspense and are about parallel dimensions ,while someday or one day is about second chance , oh my drama lover the main topic is Crossword traveler . The two are awesome and worth to watch .

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

It's kind of similar, the female lead in LUTFM is technically from another world meanwhile, in OMDL the female lead entered her book and the male leads both have hidden identities and also search for the people who caused misfortune for their families

Both FLs enter a fictional world (game vs. novel) where they fall in love with an unimportant supporting character and must attempt to save him.

Similar stuff FL travels into a story and messes with stuff. It was a good watch. Haven’t seen much of “oh my drama lover” though.

Unexpected tells the story of a man who is transported inside the world of his own manga (manhua).

The general plot is very different but they both feature the 'trapped inside you own story' story.
