I'm going to reply because you took the trouble to write a lot of text.
This isn't the first request I've received to turn this game into a hentai one, and I'm already a bit tired of reading them, but this is a good moment to reaffirm my stance.
I don’t intend to make that kind of game here. I wanted the game to have fanservice like an anime, and that's why it has certain elements that, according to you, give the impression that I was aiming for something else—but that's not the reality.
You can take the blood-sucking mechanic as a metaphor for sex, as many vampire fictions do. After all, it represents a connection between the player and the vampire. However, there won't be anything beyond that.
The game is what it is. I hope people accept it or find another project that meets their expectations.
