If you were to make a fanfic for people to read and nobody even pays attention to it, what do you do and how do you react?

I'm not a fan of fan-fic anyway, but why should you care to be honest? Although it's nice to get feed-back from readers and that, it doesn't really matter if people read it or not. If you like writing fan-fic then carry on with it, who cares what other people think?

Delete it.

It gets annoying, but I just write what I want.

get mad. but I have 1 fanfic and have a million fans already (which surprised me) so I don't hafta worry that much.

they are worth reading, but people dont have a lot of time on their hands anymore. like my story that i posted i think a year ago, One Among Us has barley gotten any reviews. and i finished that book and im on the second one now, and still no one is reading my stories. i also have Forgotten Angels, one im thinking about making a trilogy but i keep writing cause even if no one reads them on here, they might wen it gets published

Honestly, if I wrote fanfiction, it would be out of boredom, to get all the craziness and creativity out of me.
I don't even care if anyone reads it. And even if I was a professional author or artist of any kind, I would do my job for myself. Not to be popular, or to gain publicity.

It happens to everyone, don't worry. Just don't get discouraged, and write a different story. Also, posting a new chapter in one of your stories helps, because that gets it back on the front page.
