In a dystopian world where emotions are commodified, players assume the role of a Heart Collector, a rogue operator who trades, steals, and swaps hearts among the citizens. Each heart carries the memories and emotions of its previous owner, affecting the player's personality and choices. As the story unfolds, players must navigate the treacherous social hierarchy, face moral dilemmas, and ultimately choose between building genuine connections or manipulating others for personal gain. With branching paths and multiple endings, the fate of the Collector—and potentially the world—rests on the decisions made throughout the game.
