In a world where individuals can swap and borrow emotions, you play as a gifted Emotion Weaver who unexpectedly comes into possession of a heart that can dictate the fate of its owner. As you navigate through the tangled web of emotion-driven decisions and relationships with quirky characters each representing different aspects of humanity (joy, envy, courage, etc.), you unravel deeply-personal stories while confronting your own emotional baggage. Your choices will lead you down multiple paths: will you use this heart to uplift others, or will you exploit its powers for your own desires? The game challenges players to reflect on their own emotions while forming bonds and making sacrifices.
