In a world where emotions are physically manifested and traded as currency, you are a 'Heart Merchant,' a rogue dealer who obtains and exploits the emotions of others for personal gain. After one fateful transaction goes wrong, you suddenly find yourself slipping into the emotions of the heart you sold. Now, you must navigate the intertwining lives of the former owner and others affected by their emotions: a jilted lover seeking revenge, an artist trapped in a cycle of despair, and a politician hiding a tragic secret. Your choices will lead to dramatically different outcomes, and you’ll have to decide who gets their heart back. Will you manipulate emotions for your advantage or find redemption in their shared pain?
