In a world where hearts hold the memories and emotions of past inhabitants, players assume the role of a wandering soul on a quest to reclaim their identity by jumping between hearts residing in various hosts. Each host embodies a unique life and experiences, and players must interact with the complexities of their lives to learn about their own. As players navigate through dramatic life scenarios—love, betrayal, joy, and loss—they unravel clues about their true self. Choices impact the direction of the story and the relationships built with each heart's owner, leading to multiple endings based on the connections formed throughout the game.
