In a world where emotions manifest as physical entities, players step into the shoes of Alex, a 'Heart Handler' who navigates a vibrant yet tumultuous city where people's hearts can be swapped, sold, or stolen. Players must engage with different characters whose feelings have gone awry—an overly dramatic artist, a lovelorn musician, and a jaded politician—all while piecing together a mystery that threatens the fabric of emotional balance. Choices made will not only determine relationships and outcomes but also affect the atmospheric vibration of the city itself, resulting in varied endings uniquely tilting towards romance, comedy, or drama.
