In a world where hearts are metaphorical currencies, players navigate through a sprawling city where they must collect, trade, and sometimes steal hearts from others to access new areas and unlock powerful emotional abilities. Each heart is tied to personal stories and dilemmas, challenging the player to confront and reshape their own identity and relationships. As they interact with various characters—each with unique backstories and emotional baggage—they must decide whether to help, hinder, or manipulate these connections, ultimately uncovering the truth about their own heart's origin. Choices matter, and each decision can dramatically shift the narrative's course, leading to multiple outcomes and endings based on the player's emotional influence.
