Its probly the callisto hunt thing so Roana probly left her at the orhpanage to keep her safe and she might've been threatened to reveal Heilin's location cause she's the only girl born in callisto for the first time in a hundred years and maybe she sacrificed herself or something to Asura(or the sword or something) to make everyone forget Heilin but in replacement of that Heilin and the Duke would also forget her and along the way probly died or something like that? ¯_(ツ)_/¯ istg if i'm right- or what? Roana died while giving birth to Heilin or some and from trauma Duke forgot his memories?? Cause from what ik this is most definitely WMMAP inspired the hair color, the steps ting if Roana died from giving birth that'd just be- a literaly copy so I hope it isn't like that but I also hope its not like what I first said cause there'd be no point of me reading if it was like that
Hmm...I think its the same reason as the princess in the trash can manhwa the girl was found in the old castle by the emperor but the emperor doesnt remember the girl and the girl's mother. But it made the emperor so certain that the girl is his daughter because she has the trait(?) of their family. The emperor lost his memory of his daughter and wife when the wife died. Probably that is also the same to what happened here. The fl's mother, Roana, died and the duke lost his memory after her death. I dont know how the fl ended in the orphanage but it could be that she was found by someone when the mother died after getting pregnant and took her in the orphanage or the mother left her in the orphanage (Which I think its also less possible, I mean she is a mother she could have left her child to the father or something came up and decided to leave her in the orphanage) but who knows? This is just my theory(?) or possiblity
