In a peculiar world where emotions take physical form, you play as a heartfisher, someone who collects and trades hearts from different residents of the bizarre town of Hematopia. Each heart, embodying distinct feelings such as joy, rage, sorrow, or hope, has its own personality and quirks. One day, you accidentally fish out the heart of a reclusive and powerful emotion, throwing the town into chaos as everyone wants a piece of it. You must navigate social absurdities, forge unexpected alliances, and uncover the secrets behind feelings in a twisted quest to restore harmony or reignite discord. Choices you make not only influence the plot but also how your relationships with the hearts evolve, leading to multiple unique endings.
