Honestly, I don't know why I keep on reading this genre.
The authors either have the heroines be unable to understand that them going in the story changed the entire ducking story.
Or they make the original main characters for the story they got in somehow evil for no reason at all other than the fact that he wants to make the original villainous into a tragic heroine.
Or the original heroine gets possessed by somebody who thinks that everything will go right just because they are a heroine and forget exactly why heroines were loved in the first place.
And I personally think all three of these tropes are bad...... And yet it's almost always done in these stories and I still read them....
An otome game themed manga that really flips the script on the heroine character is "An otome heroine's fight for survival". Here's the synapsis on mangadex:
"Orphaned by a monster attack on her village, young Alicia spends three horrid years in an orphanage before finally running away. When she flees, however, Alicia has a violent encounter with an older woman hell-bent on killing her. During their tussle, she comes into contact with a strange crystal that bestows upon her a wealth of knowledge, transforming her from an innocent child into a cool and calculated planner. Now aware that she was meant to be the protagonist of an otome game and disgusted with her supposed fate, Alicia decides to take matters into her own hands and become strong—by any means necessary. Using her newfound knowledge, and with some help from a stranger she meets in the woods, she learns to survive by herself in a world far too harsh and unforgiving for a girl her age. Ready or not, she’s determined to carve her own path."
