mysterious_being Imma jump on this question; even though, I wasn’t mentioned. 😂
Unfortunately, WN has clear favorites on what kind of content it likes and usually ends up as popular. Those are 1) romance, notably CEO, revenge, transmirgration or reincarnation ones; 2) wuxia/xianxia cultivation; 3) monsters/hunters capturing/taming/battling; 4) video games with OP MC and RSSG-like dynamics or virtual reality qualities; 5) anything R-18 which may or may not have harem and mixed genres/types of the previously 1-4 mentioned, and 6) fan fiction of popular stories/movies/shows etc. that likley includes 1-5 genres/types mentioned.
As for your story, to be honest, it reminds me of many stories that I’ve seen that’s written well enough for WN standards and does something different, but because of how the site is set up, aka poor exposure of new authors and hidden gems that are unique to the mainstream stuff, it takes a long time for such stories like yours to get traction. And especially since you’re new to the site, it’s even harder to get noticed. In short, what I’m trying to say is that no matter how good of a story and writer someone is, they may no get the possibly warranted exposure and popularity.
So waste of time? That’s debatable. If you love writing and find it enjoyable, I say just continue without an expectation of something more. Over time, you might even get to that success or popularity. Daily updates, or just frequent ones, regardless of story quality, is also very popular on WN too. So if you keep at it, who knows? There have been stories that don’t fall into the 1-6 mentioned or have daily updates and still get notable success. Grinding for reviews definitely helps along with reading and commenting on other stories to get your name out there. Good luck! (:
