In a futuristic world where emotions have tangible forms, you play as a heart-swapper, a rogue mercenary who trades hearts with clients as a last resort in their dramatic lives. Each heart you acquire brings new relationships and moral dilemmas, as you must navigate the tangled web of emotions, conflicts, and desires of the people from whom you take those hearts. Will you use your power to manipulate, help, or destroy? Your choices will shape not only your fate but also the emotional landscape of the entire city.
