Honestly your story is one of my favorites and that's saying something since I've been reading for 4 years, and I thank you deeply for continuing your story despite your dwindling community of readers (that's more than most authors can say). And as for why you have less and less readers since chapter 180 is probably because you started to make something looking like a harem and there is a LOT of haters against this genre, I for one sure hate harems, but as I've said your story is one of my favorite so I can overlook it.
