In a world where emotions are tangible, players assume the role of a 'Heart Dealer,' a rogue who trades in hearts to manipulate feelings, uncover secrets, and solve personal dilemmas of clients. Your job is to locate the heart of a missing person, venturing through a city split into districts ruled by various emotions—fear, love, anger, and joy. Choices will lead you to heart-pounding revelations, dramatic confrontations, and unexpected alliances, all while you try to avoid the emotion-driven backlash that comes from the residents of these districts. You must decipher the clues of past relationships, whispered secrets, and emotional turmoil to find the heart hidden in the web of human connections.
