Yes and no. She was promised to be sent back to her world by playing the role of Biche. She should be sent back after dying as Biche just like the novel.
So she thinks she didn't play the role right and that's why she was sent back. Honestly normal people would probably go mad. I know I would. I'd be like since you won't sent me back I'll f*ck up this sh*tty novel again and again till I'm sent back... I mean... can you imagine just how torturing it must be for someone who have a happy modern life to be thrown to that king of world? My first thought would probably be: f*ck it being rich nobility! Gimme my smartphone and internet back! My air conditioner! My comfortable modern life and my tested and save for use beauty products!
That life must be hell to her... ╮( ̄▽ ̄)╭

Nope...i think in the first try she followed the story, but the original Biche personality could have been different, so even if the events were the same, the supposedly tyrant personality changed in a kind way...
This time i think the male lead remembers the past, so he won't be mad at her because he remembers that she died for him and he would like to treat her well...so i think he would be mad only if she died again and left him alone..
Forgive me if I'm wrong but this is her 2nd reincarnation right ? First time is when she followed the script and died, now is the 2nd time. It doesn't cross her mind that maybe following the script of the novel is the wrong way ? Like why would she has to restart again if she already follows the plot in first trial ? I mean normal people would think : wow, maybe I should try to change the plot, right ?
