In a near-future city where people can trade emotions and connect their hearts with others, players step into the shoes of Kai, a 'Heart Broker' who specializes in customizing emotional experiences. One day, Kai stumbles upon an illegal black market for hearts that holds the key to the disappearance of several citizens, including their best friend. As they navigate a maze of moral choices, personal betrayal, and unexpected alliances, players must decide whose heart they want to take, exchange, or protect while uncovering a conspiracy that threatens to redefine love and connection in their world. With each emotional choice leading to branching narratives, the stakes rise as players learn that some hearts are not meant to be traded.
