What would you do if your best friend/lover died? Castiel couldn't live without him, he was sad, depressed, anxious, he couldn't eat or sleep, since the day DW died he couldn't get out of bed, until one day, he met someone who was going to change his life forever. What will Dean Winchester do? Will he fall and leave everything behind or will he run away again?
What if life doesn't want them together? Or something greater?

-I don't own any of the characters, just the story.
