I mean.. that's porn logic, but sure
I can name a few decent guys of the top of my hat
Chang, Mr. Hernandez, Noah, Raul, Mr. Keeting, Novas Dad, the Russian Gym guy
but on the other hand you have guys Benjamin, Axel, the Gym Boxer Douche, the Yoga Douche, Jerry (at least at the beginning, he did grow on me) etc.
so the decent guys are either taken or too old to have any relationship with most of the girls
and Penny said something along the lines that she had a boyfriend but it quickly ended and she decided to focus on her modeling carrier after that
while I can't say if her relationship development is realistic or not, at the very least it's serviceable
there is a development happening from the initial "yes, the kid that mom once did babysit" to "yeah, the guy who supports my carrier, is nice, charming, helpful and fun to be around with"
it's definitely not the worst relationship in an AVN I have seen
and obviously still a better love story than twillight ...do people still say that in almost '26?
