In a world where emotions are harvested and sold, you play as 'Echo,' a collector of heart fragments. Each heart you gather comes with a story, a memory, and unforeseen complications. As you dive into the lives of different characters—each connected by their lost pieces—you must navigate their intertwining destinies, making choices that can mend or shatter their hearts further. Will you forge new connections, or will you exploit their stories for your own gain? The fate of emotions is in your hands, and every decision reverberates through your world.
