In a world where emotions can be physically detached and placed into 'Heart Containers' for safekeeping, players assume the role of a quirky Heart Courier. Your mission: to deliver a series of hearts to various clients at a bustling urban market, each requiring a different emotional state for their needs—be it joy, anger, or sadness. As you navigate through the vibrant market, you’ll encounter eclectic characters with unique backstories and requests that challenge your perception of emotions. Solve puzzles, make moral decisions, and uncover the mystery behind the heart you discovered that doesn’t belong to anyone you know. Can you navigate the complexities of human emotions and use them to mend or manipulate the lives of others?
