I'm not sure if you'd like mine...its a fanfic... Its called "When it All Comes Down". Not sure if you would like it. Its about John O'Callaghan from the band "The Maine" and features other members of the maine and all time low :) it deals with alcoholism.
MINE. Well, it's not really original. It has Christian and Gloria from 21st Century Breakdown in it, but it's my idea, and my plot. It's called 21st century breakdown as well x].
hmm. i don't know. mibba is mostly fanfic but you do find the occasional original story that's pretty good.
not to totally pimp myself out here but i have a couple originals if you want to check them out (though i wrote them a long time ago so i can't vouch for how good they are)
http://www.mibba.com/story/heartache-2-sing/A-Swirl-Of-Red/ [secondary characters are from a band but they're not like "OMG we're rockstars"]
http://www.mibba.com/story/heartache-2-sing/My-Favorite-Part-Was-Dying/ [technically a fanfiction but it takes place in such an alternate universe that i almost wouldn't count it as fanfic. i only used band members' names to get more people to read it. lol. so much for artistic integrity]
I don't read many original stories, but this one is my favorite original story I read: http://www.mibba.com/story/_92984/Rainbows-and-Daisies/ I don't know if you're into slash, but this is a really good story. It's finished. Here's the link: http://www.mibba.com/story/_57520/Ecstacy/
Just make sure to remove the automatic spaces mibba puts in links.
I'd suggest mine called Nothing to Fear but Fear herself but I'm not sure if it would be considered what you would like. Though it's not fanfic, or anything resembling it. And I suggest some of my friends on my profile page. Check it out. I'd appreaciate a comment too! :D
