I'm sure she has her circumstances, and I'm sure there will be growth in the future given the nature of the plot etc, but I'm not sure what to think about how they've written the girl to seemingly be completely incapable of listening to what the protagonist says about his father.
Like I'm really hoping the author is aware of the irony of someone saying "I'd like to sever the connection between our families" while ignoring someone's insistence that they've severed their connection to the same lineage...?
