In a world where emotions can be physically extracted and traded like commodities, you play as a heart collector named Ren, tasked with tracking down stolen hearts and learning to navigate the tumultuous relationships of their owners. Each heart carries memories, emotions, and a part of its original owner’s personality. Your choices will determine not only the fate of these hearts but also your own emotional journey in a society that values feelings more than flesh. Engage in tense negotiations, uncover hidden plots, and piece together a mystery that goes deeper than the physical realm as you try to return the hearts to their rightful owners or exploit them for your own gain.
