Lol…gotta remember her dad was use to acquiring whatever/whoever he wanted through charm, persuasion, money, etc until he no longer wanted them. So of course he instills that same concept in his children…if his daughter wants a powerful priest boy as a pet and he poses no harm then why not?
"Do you know this pet?"
Why is the father so quick to accept she has a grown boy for a pet??
In fact, why did everyone just go along with it??
