    This is a criminal Dust x innocent/depressed Classic. It does not start out with them liking each other and Dust and Blue are together for a while along with Classic and Fell. Yes this does involve Blue and Fell cheating. Anyways this is only my second story so if you don't like this ship don't read. Please enjoy. Just a side note there are side ships that will be added.
