In a not-so-distant dystopian future, a mysterious organization has developed a technology that allows them to manipulate emotions and memories by trading hearts between individuals. You play as Alex, a heart trader who awakens to find that you've randomly been given the heart of a famous (and highly controversial) historical figure. As you navigate this labyrinth of identities, you must uncover the truth behind your new heart’s origin and decide whether to keep it, trade it, or destroy it before powerful enemies can exploit it. Your decisions shape not only your fate but the fate of those around you, leading to multiple endings that challenge your moral compass.
