Though, considering that this was generations after Lotti, say Lotti's child gets black hair and that child's children also get black girl despite getting married to other people in that world where black hair isn't common.
Either the black hair genes are extremely string despite only coming from 1 ancestor, there was invest involved, which wouldn't be surprising because you know royalty, or well, ko logical explanation. It's a manhwa.

Can i get what happens to the cousins and the other red heads?
Who did both the did marry?
Why did Aria have black hair when Lotti got her father's blonde. I mean I know that genes could be recessive but are the fathers genes that weak?
Lastly, i really just want to see more cute boys do can is we the current emperor? XD
