In a bizarre world where people can trade and temporarily wear each other's hearts, you play as a heart broker navigating a realm where emotions dictate power. As you collect unique hearts with different emotional traits (courage, love, fear, anger), you unravel a conspiracy that threatens the emotional balance of society. Your task is to find the missing heart of the city’s leader while managing your own emotions — because wearing a rival's heart might just turn you into your nemesis. Each decision impacts the emotional fabric of the world, altering the story's outcome in unexpected ways.
