Extraordinary You (2019)

- The main theme in both dramas is attempting to change the future through shifts in behavior/actions for expected events
- Everyone’s fate seems to be at the whim of a greater power (SoOD - time travel, EY - the writer)
- Both couples have an epic, “star-crossed lovers” feel
- The main characters for both dramas are high schoolers

Boys over flowers has F4, extraordinary you has A3. Guys are fighting over the girl they want. They're both set in prestigious schools. If you liked extraordinary you you'll more than likely like boys over flowers too and vice versa.

The heroines discover that they are the secondary characters of the novel and want to change their destinies at all costs. Although the Drama is historical, we find this same determination in heroin

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.

The fact that people begin to act by themselves in a world written by someone else reminded me of Extraordinary you

Both are cute romance dramas , with couples with a lot of chemistry ,romantic cute tall boys and cheerful and lovely small female leads ,really good Doramas .

Similar premises, main characters are in a fictional world where they are unimportant side characters. Both take us through the journey of changing their fate

Both deal with animation.
Both romances.
Both have love triangles.
Both fun and lighthearted.

Extraordinary You has more storylines and characters. It's more fantasy based and magic based, while Yumi Cells (2) is about inner feelings and thoughts. But they both have the same Webtoon feel (probably because they were both Webtoons/ have Webtoons in their plots).

CONCEPT
- Portrays changing one's fate that could lead to a harming effect
- Has connections to the past period but a different aspect

Both dramas are set partially or entirely in the world of comic and one or both of the leads are characters within that comic.

Both FLs are self-aware and supporting characters determined to change their fate within the world of a novel or manga. The ML also becomes self-aware and work together to change the story. In both dramas the characters are controlled by the author against their will during a scene, but off-scene are free to act as they wish.

In both dramas the leads (and more characters) are connected by a past life. In Extraordinary You it's a "story" but it still counts as a past life since for the characters it was their life. In both cases it's revelead in later episodes that this other life exists and what happened in there and how it connects the leads and the other characters.
Also *spoiler* in both cases the FL forgets about the ML towards the end but the ML remains by her side anyway, trying to make her remember they were in love.

Well both of these dramas/lakore are different they both have 3 similarities
1) both of the dramas the girl falls in love with someone she can't
2) the girl knows about a book
3) the boy/ everyone in extraordinary you where in a book

Both have a plot in which a fictional for us novel or drama series are an actual world for the heroes who lives in it.
A heroine with unfortunate future fights from within to change the ending to her likings.

Similar premises. LfLS takes place in a video game(based on a novel) and Extraordinary You takes place in a comic. The main characters in both are aware that they are in a fictictional world and have to change the original story in order to live.
