Quoting this after almost a month, but I feel like you should keep going with your original plan of keeping the story between these two characters, many devs make the mistake of branching out too much and stretching far too thin, to the point that little to no substance is left or badly rushed.
On the other hand regarding the future and other projects, I'd love to see you delving in other stories where for instance you'd build a story revolving around NTR from the ground up to the point it makes sense (even a ntr spin-off on Jen complementary to this very game if you'll ever feel like). Same for a Harem centered story and any fetish you might enjoy writing a story on.
All of this to say, stick to your original plan and the game will remain as wonderful as when I first tried it, keep up the amazing work!
