A lot of people just read quietly most of the time. What you could do is to add a poll at the end for feedback purposes. Just a simple "do you like it?" with some options should do, and it's at least some feedback.
I'm pretty sure a lot of writers experience the same thing you do.
EDIT: I went and checked your story, and your first chapter had 129 total views. That's not a lot imo. Your "3.8k views" is cumulative of all the chapters. Since you have over a hundred, that's averaging around 38 views per chapter (which obviously isn't accurate since most views are skewed towards the start). Honestly not a whole lot.
I'm not sure how SH calculates algorithm, but me not reading it but opening it will already add to the tally if I'm not wrong.
