Sorry to say this, but there is really no difference between Nagpal, and writers like you. Both of you have done the same thing. Disappointing your viewers / readers. You both promised them to tell them a story of their beloved couple and you both abandoned that story midway.
You thank your readers for the love and support they give your books, and how do you repay that support? By letting them down. You say you no longer ship PRANBIR. That's fine. But did you bother to think about those PRANBIR fans you strung along, chapter after chapter, promising them the next chapter, until out of nowhere declaring that you won't further update your stories??
That's a blatant disregard of your loyal readers and followers. I am really feeling glad that I didn't follow you back then and start reading your stories, otherwise I'd be going through the same disappointment today.
That's the reason I have adopted the policy to ONLY read the completed stories. I really despise the writers that leave stories midway without any reason
