In a world where emotions can be physically transferred, you play as an underground 'heart merchant' in a chaotic city where love is a currency and heartbreaks are business opportunities. One day, you accidentally acquire a powerful heart that holds the memories and desires of its original owner. As you navigate dramatic encounters, strange relationships, and shady dealings, you must decide whether to keep the heart for your own gain or return it to its rightful owner. Each decision will not only affect your fate but also the emotional landscape of the city. Will you play it safe for profit, or take a risk for the sake of genuine connection?
