Someone please explain again how she and her father are related?

They aren’t she’s adopted actually, she died multiple times in different timeless and he fell in love with her soul when she was inside “her mom body” but surely died again and reincarnated but “her father”(also past lover before she was reincarnated) doesn’t know that the woman he’s searching has her soul inside the daughter he adopted

Then who is the biological father of her current body?
