In a dystopian future where emotions are traded like commodities, you play as a Heart Broker—someone who negotiates the buying and selling of people's emotions. Each day, you navigate through high-stakes transactions in the underground markets of a neon-lit city, collecting secrets and bargaining with powerful factions to discover the source of a deadly new emotion. Engage in rich narrative choices that affect your character's sanity and relationships, unearth dark truths, and outwit dangerous opponents. But one question haunts you: whose heart will you ultimately choose to keep, and what will it cost you?
