As you navigate the city's underbelly, you must make choices that impact not only your own heart but also the lives of others. Each heart you acquire has a unique story and background, revealing secrets, romances, and betrayals.

Your decisions will shape the fate of the city and its inhabitants, leading to multiple endings based on the hearts you choose and how you wield them.
