In a dystopian future where emotions can be harvested and traded, you play as a heart merchant navigating a shadowy underworld. Your journey begins after you accidentally acquire a mysterious heart that pulsates with the memories and emotions of its former owner—a renowned artist who seemingly vanished. As you delve into the artist's past, weaving through romantic entanglements, betrayal, and guilt, you must make choices that affect not just your fate but also the fates of others entwined with the heart. Are you willing to make sacrifices for love, or will you exploit emotions for profit? Every decision unravels a different path, and every heart tells a story, but whose heart is it anyway?
