1) Personally, I'll play the uncensored version game lol. But I'm okay with censorship too.
2) YAASSS!! I loved a man as refined as Rei (and rocking in turtleneck shirt)
3) Aiden x Rei and Jun x Rei. For Jun x Rei, I for one, have a thing for rekindled relationship/exes lol
4) Mostly I expect how the significant/small differences between each routes and the interaction between Rei and the love interests depending on the routes. It just adds the flavour to the story~
