What do you think about this situation?

It’s fine that her dad (I thought it was her brother ?) confronts her if he heard rumors, but really he should ask and not tell (show some respect for your kid, dude!). The problem is that her response options are limited to “Ok“, meaning that she can’t even defend herself. It’s a flaw in the story progression system.
But then again the 0 personalities and the lack of real consequences in this game is probably the reason these non-sensical pop ups pop up...
