In a world where emotions are physical entities, players take on the role of an Emotion Broker, tasked with collecting, trading, and sometimes stealing hearts to maintain the delicate balance of a city where various factions control different feelings. With the power to manipulate others' emotions, players navigate a web of betrayal, alliances, and unexpected romances as they uncover the mystery behind a heart that seems to be controlling the fate of the city. Every decision influences the story and the hearts of those around them, and the dynamic narrative evolves based on their choices, leading to multiple endings that reflect the complexity of human emotions.
