In a quirky town where people's hearts literally exchange places at random, you play as Charlie, a cynical yet charming heartologist (a doctor of hearts). Due to a catastrophic mix-up during a town festival, you've been bestowed with the ability to see and control where hearts go. Each chapter introduces new heart owners, including a lovesick octopus, a con artist cat, and a disgruntled old man who’s secretly a retired superhero. Solve puzzles, sway emotions, and dash through hilarious mishaps as you try to return each heart to its rightful owner before the festival ends. Will you learn to love again while laughing your heart out, or will you end up heartbroken yourself?
