I read the novel, prepare yourself.
He found out the power in her family to do the loop, and how it's passes by the women when they get pregnants.
Basically he knows that if she ever gets pregnant she is free from the loop.
BUT when he found this out, he decide to make her infertile.
Because to him she is like a godness and she sould live forever.
SO ALL THE LOOPS SHE IS HAVING UNABLE TO GET PREGNANT AND FREE HERSELF FROM THIS TORTURE IS HIS FAULT.
HE BROKE HER SO MUCH, THAT EVEN WHEN SHE ENDS THE LOOP, SHE NEVERS RECOVER HERSELF, SHE BECAME CRAZY FOREVER.
He knows everytime she is suffering, He knows that she is in the loop.
AND THERE ARE PEOPLE DEFENDING HIM, SAYING HE IS A GOOD GUY.
THESE BITCHES NEED TO PASS FOR SOMETHING SIMILAR, IF THEY LIKE HIM SO MUCH.
Oh shit, I'm sorry I totally forgot to answer.
In her penultimate life, when she dies and comes back to life, ML miraculously starts to remember other timelines where the protagonist died. He goes a little crazy, who wouldn't? Anyway, the protagonist manages to get pregnant by him... I don't know how much I can tell you about the story, because this is one of the best parts and I don't want to ruin your experience. FL and ML decide to get revenge on Dulan, making him remember the past so she can free herself from the curse. The only way to do this is to make her die by Dulan's hands directly. So she makes Dulan stab her in the stomach, killing her and the baby. ML didn't want this ending, but he agrees to let FL do whatever she wants. Then she finally frees herself from the curse and goes to the next life free, staying with ML. Dulan, seeing everything he caused, still doesn't regret it. For him, being able to go back in time is a gift that makes her a goddess.
In the end, FL, ML and Dulan remember all their lives. And FL decides to leave Dulan alone, because he is tormented by what FL went through and by her having lost the power to live forever.
In fact, the plot is more complicated than that and I would have to write a longer text to show the complexity of everything. But now I'm studying for my final.
If you have any questions, you can ask, and I'll answer later.
Someone spoil me plz? _(´ཀ`」 ∠)_
What does dulan know and how is he connected to Karen's resetting?
