A/N i'm not the best writer i have pretty crap grammar and punctuation this is just a fun little story that me and my friend came up with during science if you don't like it leave please :)

Calum and Bella are happy in their short relationship but they are worried that Luke and Kelli may never get togther everyone knows that they want to be more then just best friends. What will happen ? Will there relationship blossom into something more ?
A/N told you i'm crap but oh well it has to do for now.
