PLZ HELP ME FIND THIS MANWHA

basically I watched it being on YouTube. I remember it had a ml which had tan skin golden eyes and black hair he was either a prince or a king I can't remember. and the fl was either a male or a female and they had something that made them extremely attractive something like a butterfly but at the same time dangerous. the ml's mother was the same that's why he doesn't like them at the start. That everything I know, if you know the name I would really appreciate it!
