Bro lots of people on Dynasty hates aces seems like. Everytime they appear it's always a trainwreck in the comments. Empathy isn't in abundance around here I guess.
I think responses would be much different if the story didn't take such a subtle route with it, which isn't to say I find that a bad thing. I'm going to enjoy re-reading this now knowing the resolution seems to be an ace couple, but upon first read rather than having no empathy perhaps it's that people like me empathized according to our own experiences first and foremost. Which is natural, but leads to anticipating something that didn't come. Ideally I would love to see 1 to 3 chapters more going into their new dynamic, as the abrupt end really does this relationship development no favors, specifically for readers to empathize better with something they may find unfamiliar. Sorry to ramble, I'm just making a case for it not being outright hate against aces.
Personally I'm happy with the ending, aside from it feeling too quick. I'm always a sucker for a story of two people bettering each other's lives regardless of the relationship type.
