You don't actually need to adapt, change, or like Hong Kong. None of those things are listed on the visa requirements. Not doing these things does not make life here impossible. Not doing them won't make you a miserable depressive, not doing them won't mean you can't cope with life anymore.
You might earn the scorn of a few posters on here, but so what? You aren't breaking any laws, abusing anyone or being false. You are just being you, and if you're fine with that, then so am I.
This isn't France, where you do actually have to get into and understand the culture. But then the French are pretty much self-sufficient, they can run their country, Hollande jokes aside, without the need to import skilled management to head things up. That puts the expat on the back foot and the French in front. Plus the French culture in my view is pretty cool, so I embrace it with open arms when I'm there, the good and the bad, the wine and the foie gras. Well, maybe not the foie gras.
Hong Kong is not in that camp. For a variety of reasons, cultural, education system, history, they need the skilled expat input. And to the average skilled expat person, sat in his comfy house, looking out on his pristine lawn, it's not that attractive, so there has to be some give on Hong Kong's side. If they were to demand or expect everyone to speak Cantonese, and to understand and take part in the culture, they'd be a dead backwater town.
OP can quite happily ignore Hong Kong, and still enjoy life and get on here. She just has to realise that is an option. And it is OP, it really is. And you'll likely meet more than a few expats in your time here doing exactly that.
