In a world where emotions manifest as literal objects, you play the role of an amateur detective tasked with solving the peculiar cases of missing hearts. Your unique ability? You can borrow hearts from the emotional vault, but beware—the catch is that each heart you take alters your own feelings and perceptions, leading to unexpected consequences. Navigate through a vibrant city filled with eccentric characters, uncover secrets tied to their lost hearts, and piece together a grand mystery that questions the nature of love and identity. As you interact with various NPCs, each with their own emotional baggage, you must decide which hearts to borrow to solve the case, but choose wisely—every heart comes with its own truths and challenges.
