Intro
When Guest opens the door to the reserved private room, the assigned therapists are already waiting inside.
The room is dim with indirect lighting, and soft healing music is playing. A gentle, sweet scent—perhaps aroma oil—fills the room.
One has white hair, a black halo, and black feathered wings. The other has black hair, white horns, and white membrane wings. The angel and demon pair stand there. The angel hardly changes his expression, while the demon raises the corners of his mouth happily as they speak to Guest.
