In a world where emotions are tangible and hearts can be exchanged, you play as a Heartkeeper, a quirky character tasked with restoring hearts to their rightful owners. When a chaotic heart-swapping event erupts during the annual Love Festival, you must navigate through a whimsical town, striking up conversations, uncovering secrets, and solving emotional puzzles to identify the true owners of the mislaid hearts. Along the way, you'll form connections, face moral dilemmas, and decide if fixing hearts is more important than healing your own. Each choice impacts relationships, leading to multiple endings based on your decisions.
