In a dystopian future, your heart has become a currency, and people trade emotions in a deadly game of resource management and social manipulation. You play as an undercover operative in a sprawling black market where hearts are harvested and exchanged like collectibles. Your mission? To infiltrate various emotion-dealing factions, gather intel, and ultimately piece together the enigmatic origins of a heart that was mysteriously stolen from you. Each choice you make alters the flow of the narrative and the emotional state of the city's inhabitants, leading to multiple endings and revealing complex ties that tie the heart's history to your own.
