In a world where emotions can be extracted and traded, you play as a 'Heart Thief' who has accidentally stolen the heart of a renowned peacekeeper. This isn't just a game of cat and mouse; you must navigate the tangled web of allegiances, rival gangs, and an underground market for emotions to return the heart. As both sides of a conflict converge on your location, your choices will affect the emotional landscape of the city, the fate of the peacekeeper, and ultimately, your own heart.
