You come to awareness in an eerie mansion where a Maid (or more like The Maid) informs you that you are the “Master” of this house and that she has been awaiting your return. “You” don’t have any memories or concept of self though and so she decides to take you through some doors – which hold memories of people who have passed through the mansion – in the hopes that it will help you regain memories of who “you” are.
