The Barista, the Burglar, and the Sofa

This is the story of twenty-three year old Remus Lupin, an overworked graduate student and underpaid barista, who comes home one day to find an exceptionally attractive man has broken into his flat. Given the neighborhood he lives in, that isn’t a huge surprise. He is surprised, though, when the burglar comes back with a sofa.
Alternatively, this is the story of how Sirius Black tries to seduce a man by slowly furnishing his flat.
