Set in a world where emotions can be physically extracted and traded like commodities, you play as a heart merchant who specializes in collecting, selling, and occasionally switching hearts with others. During a chaotic market festival, you stumble upon a mysterious, stolen heart tied to an ancient prophecy. As you navigate morally ambiguous choices and forge unexpected alliances, the fate of emotions—and the world itself—rests in your hands. Will you use your powers for good, or will greed and heartache consume you?
