If you're only commenting "can't wait for next update" , "update soon" "next update when?" and nothing else in the chapter, then don't comment anything. Having zero comments is better than these kind of comments because it makes me demotivated.
Imagine spending hours, putting your energy I'm forming words, being demotivated and still writing so people get happy with update, and you guys? You're excited for NEXT CHAPTER. Next chapter which I haven't even written yet. Please, I beg you to appreciate the chapter that I just updated, not the next nonexistent chapter.
It may sound annoying but this is literally bare minimum. And I'm demotivated so don't expect updates on unbound anymore.
Okay? Bye.
