The series typically focuses on a "personal visit" or "invitation" concept, simulating an intimate encounter in a domestic setting (the performer's "room").

In a deeper philosophical sense, this phrase redefines intimacy. Intimacy is not “into-me-see” (the cliché of mutual transparency). Rather, it is into-my-room-see . A room has corners that never see the sun. A room has dust under the bed. To welcome someone to your room is to grant them permission to find you in your weakest, most private state.
