I am fine with both sides, I find the son to be more ridiculous, since if you hit the guy at the party with a baseball bat, you would be charged with assault, assault with a deadly weapon and attempted murder, and be in jail, not being able to fly to see your aunt.
I also like the niece/aunt, and have been playing to maximize for those two and the mom, leaving the daughter alone.
I wish choices mattered though, since the MC Dad even when fully avoiding her is infatuated, rather than being for the ones you are aiming for.
