AU. Sherlock Holmes is an Oscar winning actor in a career slump, John Watson is an Everyman actor trapped in date movies. When they are cast as a gay couple in a new film, will they surprise each other? Will their on-screen romance become reality?

For John, trouble starts when a fake engagement is needed for a case. Keeping things secret turns out to be rather difficult when your brother in law actually is the Britsh Government. Soon enough whole London celebrates the happy event. To make things worse, Sherlock turns out to be a master of seduction and being 'involved' with Sherlock doesn't feel as bad as it should be...
