In a dystopian future where emotions can be bought, sold, and stolen, players take on the role of a heart merchant in a bustling underground city. The protagonist, armed with the ability to 'read' the hearts of individuals, navigates a web of deceit, love, and betrayal while trying to reclaim their own stolen heart. As players make choices that affect the emotional states of others, they find themselves embroiled in a high-stakes game of manipulation involving rival merchants, desperate citizens, and a shadowy figure determined to control the market of emotions. Your choices not only determine your fate, but shape the destiny of love and humanity itself.
