What if the only way you could get a white haired purple eyed child in their family was through inbreeding??
Back Marriage between cousins (and sometimes siblings) was common in higher class society in order to keep a bloodline "pure" or for whatever other purpose. what if the white-haired children are a direct result of inbreeding and maybe because they haven't been able to get one in a while was because they haven't been screwing their siblings and cousins( it's also worth saying that sometimes people back the ended up marrying or dating their cousins by accident because well maybe they just never met and had no idea they were related or something??)
I read another manga on this topic the guy reincarnated as a kid in a alternate universe (I'm not sure if his family was high class or anything)but when he was 10 or so his parents spilled the news that he was going to marry his sister once he was of age because I had something to do with keeping their special ability in the family I can't remember exactly but obviously I don't need to tell you that he yeeted I'm so out of that situation quickly so after going through the first few chapters I searched it up and surprise surprise
Guys I have a theory
What is the demon King I was reincarnated as Dan remember our FL was really old before she aged backwards and when Dan first Met our FL it was already a few years after the demon kings downfall so it's completely possible that during that time the demon king reincarnated and that could also explain Dan's overwhelming power
But what I still want to know is this Dan would keep that promise you made while he was still The demon King
