I think that overall this book could be put on the shelves of a book store and nobody would realize it was non-professional. The grammar is great, the concept is alright. The main issue if you're looking for popularity is that the cover and name of your story seems unoriginal. It wouldn't stand out much at all if I was scrolling through Wattpad. Another issue is that the description is a bit drawn out and the emotions themselves aren't mentioned as much as I would expect. In general, this is definitely one of the better stories I've read on here. I'll give it a 8.5/10.
If you have any more questions feel free to dm me about it.
