Isekai where someone else knows that they isekai'd

our average student Ham Dan, whose hobby was reading “Law of Insomnia” wakes up to a beautiful novel like heroine. But even in the world of fantasy novels, her role is no different. Stuck as the childhood friend of the heroine, her normal everyday life comes to an end, becoming more twisted by her strong character.

When I opened my eyes, I was in a different world. I had become the game's villainous princess, who was feared by all.
Not to mention... Completely naked men I didn't even know were approaching me left and right.
Seriously, what’s up with this situation? And just how the hell am I going to get out of this freaking game?

I reincarnated into a novel inside the body of a villainess named Elise, who was executed for killing the prince’s love. From the moment I realized this, I’ve had only one goal: escape from this world.

○ : suicide, abuse, child abuse, attempted rape (not by ML), sorta incest (one sided feelings), PTSD, panic attack, murder
○ Not labeling more, coz it seems a number realize the truth about her at diff points

Harboring an obsession with the second male lead of the novel series . Like always I write a commend about Lancelot and went to sleep. But something is off?! When I woke up my 'Favorite Character' called me milady and brightly smiled at me!
I think I won the lottery. Or I saved earth in my previous life.

Poisoned to death by her own betrothed? Eunha didn’t wake up in a novel’s story just to get killed off again as an extra. To change her story she needs a cover—six months pretending to be the fake fiancée of the novel’s male lead. But will this demon of a man help her avoid another ill-fated ending?

○ : violence, kidnapping, murder
○ tbh I loved it but later dropped it cuz a plot twist was spoiled and I hated it; twist ruined the story

I reincarnated into a fantasy romance novel I wrote 10 years ago.
On top of that, I became the villainess, Ayla, who cursed the female lead and was killed by the male lead.
Then won't it be enough if I don't become a villain?
However, before long, the days began to repeat because I didn't act like the original Ayla.
"The solution is simple: become a real villainess."
