In a dystopian future where emotions are commodified, players step into the shoes of 'Heart Venders,' mercenaries who exchange human hearts on a black market. Each heart comes with its own backstory, and players must navigate a series of morally ambiguous situations, ensuring they both fulfill the whims of their clients and uncover the tragic truths of the hearts they sell. Players must use dialogue choices, solve puzzles linked to the hearts' histories, and balance their own emotions as they confront differing views on love, loss, and betrayal. Will you exploit emotions for profit, or will you succumb to the powerful connection of a heart you cannot let go?
