Aw, thanks for all the love❤️🥰 We so glad you've enjoyed the game so far!
When it comes to the MC (we call them Vesper behind the scenes) and customisation, we can't make any promises. If we had infinite money and time we would almost certainly want to make Vesper customisable, but as it stands it's not something we have on development schedule. It's just a lot to ask of Mugi when she's already busy being a superstar in a lot of places.
When it comes to NSFW scenes, it's basically in the same place. We don't want to make any promises and then break them later if things change, but also if we find a good spot to add a bit of adult content in the routes, then sure. And if none of the main plots leave room for smut, we'll look into adding some of that good content in DLC.
