In a world where emotions are monetized and heart components are actual currency, you play as a heart merchant navigating the complex relationships of your eccentric clientele. When a disgruntled customer steals your prized collection of hearts, you embark on a zany journey across city districts, each themed around different emotions. Along the way, you interact with quirky NPCs, each representing a different heart (like Joy, Anger, and Sadness), solving puzzles and managing your own emotional state as you attempt to track down your stolen hearts. Will you be able to reclaim your collection before the Emotion Bank goes bankrupt?
