In a world where the line between life and death is blurred, you play as a heart thief — a quirky antihero who has the uncanny ability to swap hearts with others to take on their emotions, memories, and unique abilities. Each character you encounter has their own dramatic backstory, and by swapping hearts, you must solve their personal dilemmas while unraveling the mystery of your own past. However, your heart could be used against you, and coping with the emotional fallout can lead to hilarious consequences. Navigate through darkly comedic scenarios, make tough decisions, and see what happens when you finally uncover the secrets of the heart you chose. The game's choices ultimately affect the emotional landscape of the world around you, leading to multiple endings.
