In a dystopian world where emotions are a currency, players take on the role of Heart, a sentient organ seeking to escape its life as a mere commodity in the black market of feelings. As Heart navigates through a series of morally ambiguous characters—each representing different human emotions—players make choices that influence Heart's journey and shape the emotional landscape of the world. Will Heart find a way to reclaim its identity and become whole again, or will it forever be trapped in the chaos of others' desires?
