In a world where emotions and memories are tangible, you play as a Heart Peddler who collects, trades, and occasionally misplaces hearts. When you unintentionally swap your own heart with another person’s, you find yourself entangled in their memories and emotions. As you navigate the lives of strangers—experience their joys, fears, and regrets—you must solve the mystery of whose heart you have and how to return it before your own life becomes a mere echo of theirs. Engage in deep dialogues, challenge emotional dilemmas, and make choices that shape not only your fate but the fates of souls intertwined with yours.
