Up until when the 'female lead' appears, events are following the original plot of the book, including them sleeping together. In the book, once the FL appears, the ML realized that his love for the MC was only that towards a childhood friend, yet he still tried to remain faithful until he was basically commanded by God to marry the FL.

When the MC starts to realize that some events (like her pregnancy and the early arrival of the divine lady) are not occurring according to the original plot, she makes an attempt to talk to the ML and ends up witnessing first hand the ML/FL first meeting that goes according to script (including an accidental kiss). Some of this is misinterpretation, but there are also strong hints that the FL is using magic to manipulate things and is definitely a transmigrator.

Granted that she's in a dilemma because of her feelings for the duke, she has no backbone and just gets swept away. It's rather annoying as she's supposedly written where she can't stop herself and spills her regrets later--as if she's the only one who will have to put up with the repercussions of their actions.

Within the first couple of chapters, the MC sleeps with the male lead. (No smut.) Before they even get into bed, she has these thoughts that supposedly makes her cute, bantering with herself and then her mouth saying another thing. I just find her annoying at that point.

Then after that day, she avoids the dude she slept with and gives him no reason as they ended on a sweet note the day he escorted her back home. For three weeks, she avoids him and makes excuses, and then, she decides to tell him when he comes to visit her on a rainy day that she wants to annul their marriage. She doesn't give a reason why, again. She just simply says that he'll know in the future, while supposedly conflicted.

The only reason why I'm so irked is that you spent 10 years together with this man, and in those 10 years you fell in love with him. But somehow in those 10 years, you're so afraid that you can't win against the proclamations of fate that you just decide to 'escape' your 'destiny' and not bother to say anything.

Yes, I'm aware that it stated in her recollection of the novel's plot that some priest (or someone like that) received a prophecy that only this Sia girl and the duke being together will bring prosperity to the kingdom.

However, I don't think that the 'explanation' the author gave justifies anything she did. She's adult, mentally, she's a lot older than the duke is but somehow she reminds me of a preteen brat who has been spoiled her whole life. Again, she's a white lotus who is ignorant of her blatant actions that have heavier repercussions.

He's so obssesive and it keeps sending me chills man.

I don't like how she just upped and ran away without an explanation!! What the Hell girl??? I know you're being tormented by nightmares and all but shouldn't you have at least tried a little bit before you left?! You didn't say anything! Assumed everything! And left as though the ML is the one that made you go away! WTF?! You left him high and dry! You think he's a mind reader?! Every time he asks you just kept silent and answering in your head and left as though he understood why you did it! AND you're surprised why he's kept looking for you?! Didn't you have a clue that things weren't going as the novel was when there was no wedding or oracle abt the ML and Saint?! F YOU Little girl!! Whatever he does to u now afterwards will be JUSTIFIED in my eyes solely bc I think it's his RIGHT after what that FL did to him! Che!

I mean you literally had a semi romantic relationship with the ML and you don't trust him enough to consult him or even try to consider him as something other than a character in a book (*`ェ´*) I do give her some slack for trying to not leave him when she went to the Palace and all

Laure agrees to have premarital s*x with Celix when he asked if she would. She then avoids him for 3 weeks, when they finally get face to face he tells her he moved their wedding to next week, she takes a pregnancy test. Also small detail but the crown prince proposed to Laure off screen and Celix wonders if she would rather be a princess then his wife. All while behaving in the most melodramatic way possible.

First we get the typical "I reincarnated into a villain who will die at the end of the story' set up but then in chp 18 we learn that Laure did try to change fate! She tried to stop the death of Celix parents, by hindering their travel plans but they died the next day! I think that should of been in the first 5 chapters instead for its was strong evidence to her belief that fate can't be altered. Also shows not tell us why she loves Celix so much, because of her guilt for failing to save his parents she does her best to make sure he never felt alone growing up. It was a a lot more interesting then the first five chapters where she cries because the Sia and Celix are soulmates made by god, chapter 18 reveal made Laure reasons more understandable.

The ML is yandere sure but I can't seem to hate him, the dude rlly suffered when she left him, n u can't blame her for that cuz the girl was scared n tried to protect herself n her child, well at least we can pour all of our hate n frustration on that saint b*tch
