I think this is little spoiler but Navier isn't even the one infertile instead it's Sovieshu! Seems like they just never questioned it properly tho but whatever Sovieshu will really get what's coming for him soon
BYEE Ok well thank u for telling me either way, he still a piece of shit
He totally is
Both navier and sovietshit are infertile cuz of the cookies but thanks to magic(i think) navier gets cured
if i was her, i would simply say for him to FUCK OFF because now that they are divorced he has NOTHING to do with her and vice versa. I dont know why he still clinging onto after HE WANTED TO GET DIVORCED. Fucking dumb piece of shit. He got mad that SHE was literally talking to other males, even though HE WAS IN A FUCKING AFFAIR HIMSELF AND ADMITTED IT TOO. HE DARE EVEN GET MAD AT HER AFTER HE IS THE REASON FOR MAKING NAVIER INFERTILE TOO WTF FUCK THIS GUY I HATE MEN ugh. If he really wanted to be with Navier he would have NEVER gone to that piece of fucking horse shit homewrecker rashta. Omg he is so fucking dumb please please author resolve this manhwa/gua/ga/webtoon(?) soon I cant bear that to see dumbass of a emperor anymore.
