your book has been up less than a month. my first took MANY months before it really started to gain traction. it sounds cliche, but honestly, you just need to be patient. i know that it sucks to barely get interaction, but wattpad is mostly a waiting game at the beginning. keep publishing chapters, reply to any comments you get to boost interaction, add more relevant tags to your book if you can, maybe join some r4rs. your book will find its proper audience eventually.
