I've still got this plot forming but I wanted to get at least the general idea out so I wouldn't completely forget it over night. 
It's a love between a thief and princess, or not a princess honestly I don't care too much what you want to play I just have the vague idea in my head about a secret love between a thief and someone higher status that he meets because he was doing a shit job at robbing their house. I'll expand on it tomorrow, probably.
