Whose Heart Is It, Anyway?

In a near-future society where emotions are physical entities, you are a 'Heart Merchant' who trades emotions for personal gain. One day, you discover a mysterious heart lodged in your inventory that doesn't belong to any of your clients. As you delve deeper into its origins, you encounter various characters whose hidden feelings drive the plot forward. Each character offers a unique interactive experience where you must navigate their emotional landscapes, solve puzzles tied to their pasts, and ultimately decide whether to keep the heart, return it, or even trade it for something more valuable. The choices you make influence not only your fate but also the emotional balance of your entire city.
