The girl is the dead wife’s treasure, she’s entrusted to the spirit so he could eventually go get her. They didn’t know it was a child, and then the spirit went to the spirit realm.
It is fucked up because the dad paid neither kid much mind while before the wife dies she spoiled the brother. Leaving their daughter alone and forced to grow up by herself.

Hypocritical father who babies the son and child who literally looks like his dead wife by raising her to “live freely “ but couldn’t care to even/ think to do the same for the one who came from his sperm and never actually took steps towards improving as a parent towards his daughter he wronged the most and his son who actually needed a parent vs tic tok boy mom hardly truly cared about her daughter but overly spoiled the son
