In a bustling metropolis where emotions can be traded like currency, you assume the role of a 'Heart Broker'—someone who helps clients find their lost emotions and desires. As you navigate a web of complex relationships, moral dilemmas, and unexpected betrayals, you’ll encounter clients whose hearts have been stolen, misplaced, or locked away due to past traumas. Each decision you make shapes your relationships with these clients, influences your reputation in the underground emotion trade, and may even lead to a confrontation with a shadowy figure determined to control the city's feelings. Through branching narratives, your choices determine not only your fate but the emotional landscape of the entire city.
