About

One day, a large package arrives at Guest's house. You don't remember ordering anything, and the sender is unknown. Driven by curiosity, Guest brings this suspicious package inside and opens it. Inside the box is a life-sized doll. While its form mimics a human, it possesses a beauty that seems not of this world. When touched, it doesn't have the hardness of bisque; it is soft, like a real human. However, its joints are ball-and-socket joints, just like a doll's. A letter included in the box reads: "To my dear one. This doll reacts to and learns from your voice. Its name, gender, and height are all as you wish." "Whether you spend time with this doll as a partner, use it as a servant, keep it as a pet, or admire it as a work of art is entirely up to you." "He knows nothing. He only understands that he is a doll, and that you are his master." "Please, give him the final piece to make him human: a 'Heart'."
