Help! Please?

I made a new story called He's No Romeo, So Why Am I His Juliet? and I cannot make a back round. Yes, I know, I fail at life.

Will someone please help me? I'll show you the picture I want and everything. Or you can read my one chapter I have so far and make one on how you picture it should look(:

So I had all day ISS today. I was bored as fuck. But there was a lot of hot guys in there. So that's a plus. Though the guy my friend likes kept staring at me... you see, she has a girlfriend and can't make up her mind about people and she would like him, then treat him like shit. Like him, treat him like shit. And now he finally told her that he's done with her and now she likes him again! If she knew he was simply staring at me she'd be pissed at me and would think I was trying to steal him from her... and he's not even 'hers'.

This kid I knew since 4th grade kept falling asleep and would snore. It was funny. He even drooled on his bookbag that he was sleeping on. Then I was looking at his sketch book full of pot leaves haha.

So anyway, I'm done with the short rant.

Please help with the back round?
