Isekai / RPG game like / Fantasy World fever 4

After reading the book of future, she discovered she was the Saintess double who'll be killed in that FL stead. The orphan who chose to run away saved the villain and ended adopted by him. Will she finally find happiness?

Edit: i though it was isekai but it's not. She read the novel in her childhood not in another life. She's of course a bit more mature but still a kid. Some happy fluff, some anxiety ride. An ok classic of the genre overall.

Author became own novel villainess. Ended up becoming the ML's kids's caretaker. Will the road to happiness be attainable to them all?

Overall Classical but okay.
Gentle kuudere ML with madness curse (I pity him a lot). Responsible MC with strong mother instinct and sad abused past (was a teacher so kids won't suffer like her). Cutty pies twins who were saved from abused by MC (trigger warning).

Reborn as extra who'll get killed by Empress jealousy. But story seems a bit different as she met her at 5 without knowing her identity and both grow closer.

Kind adult Empress who over love MC. Cute mature child MC. Neglected ML (crown prince imprisoned by emperor).
So far lots of fluff. Classical?

Became novel villainess as kid. Accidentally seduced both FL and ML while trying to befriend them. The end.

Nothing new. Nothing much

After conquering hell, isekaied MC, now king of hell, could finally go back on earth after a 1500y and eat real food!! But with 5y gap on earth upon arrival, the king of hell discover the arrival of gate on earth and became a lv1 player?

Isekai returnee + Reverse isekai. OOOP MC nerf down to "simply" OP... has the power of gluttony and strengthen by absorbing demonic energy (found on monster)

Despite being novel FL, she kept dying after the happy ending and reset a year back without knowing why. After 100+ y stuck. What is real or not? How to break out of this repeated hell? Why not try revenge? Okay. In this life, the lady choose to be a murderer.

Psychologicaly incredible. MC is clearly going crazy. This isn't even a revenge isekai. Everybody's sus, everybody's kinda crazy. And this time even the isekai part isn't sure. I have hight hopes for so much mystery!

Yoga teacher transmigrated as novel extra and saved the Prince for the OG soul.

Cliché plot where everyone misunderstand her action as romantic choice like she could only do all those smart things for romance only. Kinda frustrating and blend execution for me. Magic sliming down. A miss for me unfortunately

Reincarnated as romance novel FL, she was headed toward the happy ending but... why did the genre changed to horror? For happiness, what has to be sacrifice?

Isekai romance turned zombie apocalypse. It is more a survival that a horror story. Definitely not for the soft heart but it isn't hardcore gory either. The characters evolution is super interesting both MC and the "extras". I'll stop here to avoid spoil but this story is worth giving a shot in my opinion.

Cf summary

Too few chapter to judge but cute kid MC, mix of child and adult behavior but she was already had low self estime. Mysterious eerie ML. Kuudere dad and brothers except the 3rd one who's a tsundere XD

Reborn as background princess in a gender bender romance novel. Unexpectedly being escorted by the FL disguised as a male by magic to the capital and getting in a contract engagement but... turns out the expected FL was really a male?!?

Mmh... not sure if i like MC or not. I like her freespirit but at the same time she sometimes can be a bit too careless which kinda frustrates me? MC was male twin who survived instead of female one unlike OG novel, hence MC confusion.
