In a world where emotions are embodied by physical hearts that can change hands, you play as a barely competent heart merchant who must navigate the treacherous marketplace of feelings. Each heart you sell or trade is tied to someone's memories and feelings, and customers are usually much more than they appear. Choose wisely which hearts to engage with, and from whom to acquire new ones. Balancing your own emotional baggage while attempting to help others find their real selves leads to comical misunderstandings, unexpected alliances, and a quest that reveals the true meanings of love, loss, and laughter.
