In a world where emotions are commodities and heart transplants are a matter of trade, you play as an emotional broker in an underground market. Your job is to negotiate the purchase and sale of hearts—each imbued with unique traits and memories. One day, you acquire a heart that doesn't belong to anyone on your list. Rather than going by the book, you decide to dive deep into the backstory of this heart—encountering the inner thoughts of past owners, their regrets, and the chaos of their relationships. Your choices will influence not only your future but also the intertwined fates of those who once loved, lost, and learned through this peculiar heart. Can you find out whose heart it is before the emotional market explodes?
