In a world where emotions and memories can be harvested and traded like currency, players take on the role of a 'Heart Broker,' a skilled negotiator moving through the fractured relationships of a bustling metropolis. Each heart contains memories, emotions, and desires of its previous owner, which can impact the city's inhabitants in unexpected ways. Players must navigate complex moral dilemmas and character relationships as they broker deals with clients seeking to change their lives — or exact revenge. Decisions made will alter not just the course of the game, but also the players' own heart, leading to multiple possible endings and a deep emotional journey.
