Suggestions: Do something about the lyrics. Maybe you can make them cursive, just to point out it doesn't really belong to the story?
It's a little hard to read now... and you could get rid of all those ~~~~ thingys. *twinkle*
Other than that. Who, pretty tough to split up on your wedding day, in front of the preacher. *lol* Maybe you could spend some time and work on it a little? Like tell the reasons she fell for Malfoy at first... write a little more about the splitting up... such things. It's really short, and leaves a lot of questions unanswered...
And also I saw quite a few spelling mistakes "care less" you wanted to say, not "careless", right? Things like that. Just run over it again.
And I wouldn't say the story sucks, no. But if you took some time and work over it, it would be so much better. *twinkle*
I really like the way you added lyrics... I always do that, too. *lol*
Still I am really glad Ron got the girl in the end. *lol*
Take care, Flutterflie
