Sexual attraction and affection can be very opaque in their manifestations and don't always follow the logic you'd expect.
I agree, and the "unpacking" is just an exercise in examining possible factors. We're all inadvertently influenced by the weirdest things and I find it fascinating. I wouldn't expect that sexual attraction could be "gamed" in any way, we like who we like and that's that, really.
It can change over the years, I'm talking preferences here not sexual orientation, but I doubt anyone really succeeds in convincing themselves to feel attracted to someone. Even stories about arranged marriages are quite unspectacular in their depiction of the "and then we fell in love" moment; unfortunately women can get used to anything and have had to, for centuries. So "he turned out to be not too bad after all" about a man you had no choice in marrying isn't exactly analogous to the old Diet Coke adverts in the 90s with the women breaking their necks to sneak a peek at the fit bloke.
What's interesting also is the "just give him a chance" rhetoric that is very, very straight, and very sexist. There's no media cliche that says the opposite. No dowdy girl hero who gets the guy in the films. No "man as plot device".
"Try it, you might like it" is just "you haven't met the right man yet" and "just give him a chance". It's always about men getting their way with disinterested women, and never the reverse, and it is very clearly in play here. Manipulative behaviour, rapey behaviour, male behaviour.
