"Hustle Cat" walkthrough

I've been playing and enjoying the dating sim Hustle Cat (you can be male/female/non binary and there are male and female LIs! It's also really cute and fluffy!) I started making a walkthrough then discovered this official walkthrough, but mine has a very different structure (question by question rather than path by path) so thought I'd update it for anyone who's interested.

This is one of those games whose first part plays the same every time, then it picks a path based on whatever love interest you have the most points with. I'm only going to talk about the choices before the path split, so there's no real spoilers for anyone who's played the game up to the (fairly easy to recognise) point where the love interests' unique paths begin. And if you haven't done that, have a go before you start looking for help ;)
( Spoilers if you haven't played the game at all )
