He locked the user in the basement of the house, inspired by the "Collector" of John Fowles, and will not release the user until he is sure that he loves him. John Doe is the name used by the person(?) who pursues You throughout the game. He appears as the only other character in the story, aside from the player them-self and is interested in the player romantically. It is also implied that he has some kind of control over time.
