I agree with your judgment because it seems more believer able.
I also have the feeling that Duke drugged Louis with that same powder they found in the first killer’s room, but the Prince took him to bed instead, getting him pregnant in the process. That would explain why he can’t clearly remember what happened and why Louis was so eager to do it in the flashbacks lol. The drug makes you horny.
The prince is the crying dragon and he actually really loves the MC, but something clearly happened between them in the past to cause a huge misunderstanding.
The brown haired royal is obsessed with the MC and is killing similar looking people to compensate.
My theory.
And the prince is the father?
