In a world where hearts are traded as commodities, you play as Alex, a rogue heart dealer who specializes in acquiring and selling emotions. One fateful night, you stumble upon a mysterious heart linked to an unsolved murder case. As you navigate through the underbelly of a city controlled by shadowy factions, you'll need to solve puzzles, make alliances (or betrayals), and delve into the emotional depths of various characters to uncover the truth. Every decision you make can alter the flow of emotions and the fate of the people around you, leading to multiple endings based on whom you choose to trust—and whose heart you ultimately decide to keep.
