In a world where emotions are manifest as tangible objects, you are a 'Heart Broker,' a skilled negotiator who trades in feelings. One day, a desperate customer arrives, asking for a heart that has been stolen from them, leading you on a winding journey through the emotional black market. As you interact with a cast of quirky characters—each representing a different emotion—you must navigate moral dilemmas and choose which hearts to broker, which to keep, and whose feelings to manipulate. Your choices will determine not only the fate of those you encounter but your own emotional state, culminating in a dramatic showdown where you must confront your own feelings about love, betrayal, and the nature of the heart itself.
