im curious how tf he grow up to be that cold, i mean if we look at his parents its abvious that they r still in love and give him more than enough love.. so..

Could be his education.
I mean his parents are loving but to me the Emperor is the kind of man that really only loves his wife.
Also Leon could have taken up the idea of being cold equals being a good Emperor since it makes you more then human and less weak.
Or the political sphere he grew up in was so bad he cultivate his cold personality to survive and later dominate it. (I think this is most likely since we saw how he views some nobles)

The parents died when he was so young. I can only assume the political environment and being a child emperor surrounded by figurative sharks around him muted his previous open nature under his parents's guidance. Plus, he was under the impression that Lizzie is in cahoots with the dukes for his power since she hid her suffering and act perfectly like a doll that it freaked him out to the point he didn't bother to look at her and notice that she's the real victim. If there are anyone to blame, I blame all the adults around him as he grew up after his parents' death.
my heart skipped a beat when she start falling omg.. anyways that pinky bitch is creepy
