This movie is either Chinese or Korean. It talks about a young adult who like to wander his country/the world using other people's houses to rest (rather than, say, an B&B).
Once he is sure that the real house holders are out (e.g. for holidays) he enters their house and lives there for a couple of days. Before leaving, he cleans and washes everything, to return the favour.
He then knows a girl, who is bound to stay at home from her evil husband. They fall in love, he "frees" her and they start to travel together.
Any clue for the name of the film or the director?
