Because of his bloodline he needs blood (kill people) or sex. Read the novel because he took the sex route. Like they was getting down like every ch after he came back from killing the traitors. Another thing him and his soldiers could wipe out the barbarians in no time. He doesn't so he'll have people to kill and it keeps the Capital off his back.

He feels shady or like he being fake for some reason. I can't even really explain why I feel that way. Oh he's very pretty lol

It is clear that the duke has been observing her for a long time. He knew about her struggles and never looked down when she expressed her fear. His first reaction was to protect her and he knew what he had to do so that she wouldn't get too shocked. Putting his hand over her eyes illustrates his sensitivity. Later, he was the one who showed more concern for her and forced her to get treated. I feel the blond man is not sincere and uses his handsome face to manipulate the priestress.
Please go away they're doing fine now you putting doubts in his head. Pushy people are irratting i dont care if it's his aunt. I feel like the dad might come back and try to take. Wahei is going to make then leave, think about for a sec then be like "they're my family" or "I miss them" and run somewhere to get them back.
