As you navigate through a chaotic city where hearts are stolen, lost, and traded, your goal is to find the heart's true owner while unearthing a conspiracy that threatens to manipulate emotions for control. Your decisions alter relationships and the emotional landscape of the city, leading to multiple endings based on your choices, friendships, and romantic entanglements.
