In a world where emotions and memories can be literally exchanged among people like trading cards, you play as a heart broker operating in the bustling city of Pulsalia. Your job: to negotiate, barter, and sometimes swindle the diverse denizens who want to feel love, joy, or even heartbreak. Each heart you obtain offers you new insights and experiences, shaping not just your abilities but also how you empathize with others. As you navigate through a web of turning friendships, betrayal, and unexpected romances, you must decide whose heart you'll keep and whose you’ll give away. But beware — some hearts have dark secrets that put the souls at risk. Choose wisely, for your journey will lead you to profound personal discoveries that could change yourself and others forever.
