Set in a bustling metropolis where the population's hearts are literally up for barter, players assume the role of a heart dealer who specializes in trading the emotional essences of individuals. Each heart has its own backstory, abilities, and quirks based on the emotions tied to its previous owner. As players navigate this vibrant world, they must choose whether to unite hearts with their soulmates, profit from their merchant dealings, or uncover a conspiracy threatening to upend the dramatic balance of emotions. Choices have profound consequences on the city, relationships, and what it means to truly love and lose.
