In a world where emotions are literally extracted and stored, players take on the role of an Emotion Analyst tasked with solving bizarre cases across a vibrant city. Each person’s heart is a collection of quirky emotions, represented as both colorful objects and peculiar characters. As the player navigates through absurd situations and solving emotional heists, they must use wits, charm, and a bit of dark humor to collect clues, interact with eccentric city dwellers, and ultimately piece together who has 'borrowed' whose heart. Every choice affects the emotions involved, leading to unexpected outcomes and hilarious revelations.
