In a world where hearts can be swapped, you play as a quirky detective who must solve a series of bizarre cases involving stolen emotions and misplaced hearts. Each case takes you to eccentric locales where you'll interact with colorful characters who possess the hearts of various humans: an art critic who now feels nothing but disdain, a cook who has lost their passion for food, and more. Use your wit and unique interviewing skills to piece together clues, experiment with heart swapping, and ultimately decide which heart belongs where. Your choices will shape the emotions of the characters and influence the narrative's outcome in unexpected configurations.
