In a world where emotions can be physically harvested and traded like currency, you assume the role of a 'Heart Dealer', navigating the treacherous underbelly of society. Amidst a backdrop of betrayal and moral ambiguity, you acquire, modify, and trade organs from various emotional strata to craft your 'ideal heart'. However, when you discover a plot by a powerful syndicate to synthesize a new emotion—a heart of pure chaos—you must choose whether to stop them, sell out, or join their ranks. The choices you make affect not only your fate but the emotional spectrum of the entire city, leading to multiple endings based on your emotional decisions.
