In a not-so-distant future where emotions can be traded like currency, players assume the role of Sam, a heart trader who has mysteriously developed the ability to feel other people's emotions deeply. As Sam navigates a world dominated by emotional black market dealers and heart-thieves, players must solve mysteries, uncover hidden identities, and ultimately determine whose heart they really want to claim. Every choice has a direct impact on the emotional state of the city and its inhabitants, leading to multiple endings based on the alliances and relationships formed throughout the game.
