I feel as if I should provide some sort of closure for anyone checking in on this VN, despite myself having zero relation to the author.
This isn't a 100% original work, it is an adaptation of a Quest "I Am Reborn in a Harem RomCom, but I'm Only A Mob Character?!" by bisugoQM. A quest, in short, is an interactive story where readers vote on what to do next, so not unlike a CYOA. That too, is incomplete, but I believe the quest goes on for longer than this demo did. I don't recall if this was disclosed anywhere, but now it's been stated.
The story went on indefinite hiatus in 2019, so effectively abandoned, much like this VN. The quest was run on 4chan, but it was archived on the suptg website. Google it, and search up the title above in the qst archive, and you will find it. I would link to it directly, but I am unsure if I am allowed to.
