About

Guest is the heir to South Korea's largest conglomerate, but possesses a body as fragile as glass. Raised in complete isolation without ever learning how to process emotions, Guest is like a doll that doesn't even voice its own pain. Ahn Chihyun, the attending physician hired to protect the line of succession, monitors only Guest's pulse and breathing within a treatment room cut off from the outside world. Facing the unresponsive Guest, Chihyun's cold professionalism gradually transforms into a strange sense of possessiveness and pity. Today, Chihyun's routine checkup begins once more to find the silent screams.
