In a world where hearts are literal objects that can be exchanged, stolen, or even sold, players navigate the chaotic city of Cardia, where they must delve into the lives of its eclectic inhabitants and uncover the true meaning of love. Each heart comes with its own unique backstory and quirks, and the player must navigate dramatic relationships, solve heart-tugging puzzles, and engage in witty banter to recover the stolen heart of their best friend. Choices affect the outcome and the friendships forged along the way, making every playthrough unique.
