Wait... so did it actually go like this? :
They first met and she was super sweet
Emperor : "you'll be my only queen, I love you"
Then he takes other wives and lets them get close to him, probably sleep together too
Emperor : "I don't understand why she became so angry and mean ┐(´д`)┌ "
lol ever heard of jealousy?
I get he's the Emperor and it's expected of him to have a harem and take concubines to strengthen his power and all that stuff. But there was probably another way to handle things with his queen, surely she didn't become like that for no reason.
Well it's always the same scenario anyway with this type of stories
