In a world where emotions are extracted from hearts and traded like commodities, you play as Ace, a cynical heart-smuggler who stumbles into a chaotic auction involving stolen hearts from notable figures around the world. Each heart is imbued with its owner’s memories and emotions, which the players can access while interacting with them. Your mission is to track down the missing hearts, reclaim them, and resolve the threats of those who now possess them. But beware—people can get a bit 'attached' when they realize how hard it is to let go!
