The god of dreams, former god of chaos, finds himself in a tricky situation. Scared by the ephemerality of a human being's life, but intrigued by a certain human in particular, he has to make tough decisions that would affect not only his life, but also the life of the human whose humanity he falls for. You can find the original work on ao3 upon the same name but written by longing_for_angst.

*this story was written by Gibslythe on ao3* "Two whole months of free laundry in exchange for two weeks of being my fake boyfriend. Deal?" Keith hesitated for a moment. Was this really worth it? Hardly. Lance was an asshole, and he wasn't sure what fake dating would entail. But, free laundry was free laundry, right? "Alright, it's a deal." Or: Lance makes the mistake of telling his Mom he has a boyfriend coming home with him for Christmas. Keith makes the mistake of agreeing to be Lance's 'fake boyfriend'. This is actually the best fic I've ever read. It emotionally destroyed me and then put me back together only to kill me again. Read on ao3 : http://archiveofourown.org/works/7454385
