In a whimsical town where the residents' hearts can be literally swapped, you play as a cynical heart merchant who runs an underground 'Heart Exchange' business. The streets are filled with characters who have traded away their own hearts for temporary gains, from a lovesick poet who can't write a single verse without feeling someone else's heartbreak, to a cranky old man whose heart now belongs to a hyperactive child. As you navigate partnerships and rivalries, you must decide whether to help a desperate town that has forgotten how to love, or to profit from their misfortunes while unraveling the heart of your own true desires. Engage in choice-driven dialogues, form alliances, and explore the bizarre relationships born from heart-swapping in a world where emotions are just currency.
