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.
Someone spoil me plz? _(´ཀ`」 ∠)_
