Based on what I read from the raw!!!
Spoiler alert!!
Since the raws are korean I couldn’t understand it but based on the action it seems like this curse thing he has makes him go tyrant mode, his mind is like full of destruction and despair. He especially has nightmare, but then he didn’t feel any of those stuff when he saw Amelia/the bird. He felt more at ease. I think he was looking for the witch so that this curse thing he has will calm down. Plus he hasn’t been able to get a good night sleep. So with the presence for Amelie, he feels calm and at peace
Ah that helps explain some things a bit. Thank you!

What I want to know is how he got a curse/disaster/evil sealed in him. I doubt he was born with it nor did he want it so.... how? I’ll stick around for that to be explained.
