Sherlock Holmes and John Watson met through Mike Stanford, who knew they were both looking for a flatmate and set them up together. He knew they would be perfect for each other. They had grown close after just one day of being together and eventually started to develop feelings for each other. They start dating after about a year after meeting and both men are the happiest they've ever been. But then Sherlock jumps. And John waits for Sherlock to come back, for this to be just another trick. He waits and waits and waits. When Sherlock comes back, though, John has changed. And not for the better.
