Thank you very much for the detailed review, as always!
Let's see! First of all, Paul has a set personality, so it doesn't change no matter what route or decisions you make. I'll take a look at Ophelia's sprite; I know I made some changes, but I can't recall if those changes are implemented in the demo or not. Same goes for the music, so thank you for the feedback!
The stats raising part, as you can see, it's not very important in the game (although I still want to make a full dating sim one day because I love that kind of games, haha!), so I hope you enjoy the finished VN when it's ready! And feel free to suggest settings that you'd like to see in a BL game, I'm always open to ideas!
