It is extremely unlikely for a daughter to fall in love with her biological father if she has never met him before and grew up without him. Romantic love between family members, especially immediate family like parents and children, is considered incestuous and is not a healthy or normal dynamic.
The absence of a parent during a child's upbringing can lead to feelings of curiosity or longing to know them, but it doesn't usually translate into romantic love. In most cases, the relationship that develops between a child and an absent parent who comes back into their life is more of a familial bond rather than a romantic one.
It's essential to understand that love between family members should be platonic and based on care, respect, and support for each other. If someone experiences confusing or distressing feelings about family members, it may be helpful to talk to a mental health professional to gain insight and understanding. They can provide guidance on processing emotions in a healthy and appropriate way.
