Set in a bustling steampunk city, 'Whose Heart Is It Anyway?' invites players to step into the shoes of a quirky heart merchant who has accidentally collected a diverse range of hearts—each imbued with the memories and emotions of their former owners. When a powerful crime syndicate kidnaps the heart of a famed inventor, players must journey through the city, solve emotional puzzles, and navigate romantic entanglements with various characters to unravel the mystery. Each heart represents a story, and players can choose to interact with the former owners of the hearts, creating deep emotional connections and potentially altering the fates of their owners—forcing them to consider the implications of their actions. Will they recover the inventor's heart before it's too late, or will the city be lost to chaos?
