In a dystopian world where emotions are harvested and traded like commodities, players assume the role of Kai, a skilled 'heart dealer' who can infuse emotions into objects and people. When a mysterious black market trade goes wrong, Kai finds themselves with a heart that doesn't belong to them, and must navigate the underground world of emotion smuggling, alliance-building, and moral dilemmas. The choices players make will affect not only their own fate but the emotional fabric of the city itself. Will you restore the heart to its rightful owner, or will you use its power for your advantage?
