Don't get me wrong i love fan fiction, but my biggest problem is the
GRAMMAR.
I get it you are not English, so i don't expect you to type perfect English but oh my god!
I have read the beginnings of many fan fiction but honestly can only say i have stuck with two of the
1) It all started with a secret- Niall_is_irish
and
2) Louder dan x reader by I believe Hanisnotonfire
I can honestly say the both have decent grammar.
Another thing that annoys me to no end is the story progression, story progression is one of the most important part of all stories.
if you go from just meeting someone to MARRYING them the net day I swear to the good lord i will throw my computer at you!
or just meeting someone to going to the mall , there being a shooting/ hold up and them saying i will never leave you, If it were me in that situation i would be like bye bitch! and i would obviously call someone or something but i Am getting my sweet ass out of there!
So all around if you have great story progression and grammar then you have my gratitude and my vote.
