In a world where emotional connections manifest as physical hearts, you play as a heart-harvester named Sparks. Your job is to collect, trade, and occasionally steal hearts from the rich and powerful to sell on the black market. But when you stumble upon the heart of your childhood friend, lost in an underworld of corruption and betrayal, you must choose between your survival and their recovery. The game features branching narratives driven by players' choices, allowing them to forge alliances, confront enemies, and navigate the complexities of love, greed, and the illicit black market for hearts.
