Hi, I'd say they are two active, sporty young gentlemen in their late 20:s. Maybe students, maybe having their first job and mangaed to get a home of their own which they are sharing, partly because of economics (they spend all their money on bikes and cameras) partly because of companionship. It is their first real home since the moved from their parents so feels good to have a room-mate. The box is somewhat mysterious :? Maybe the lock is to prevent burglars from stealing their ale
