In 'Whose Heart Is It, Anyway?', you play as an ordinary heart transplant surgeon with an extraordinary twist: the hearts you transplant come with the memories and personalities of their previous owners. After an experimental procedure goes wrong, you find yourself experiencing emotional echoes from the hearts you've connected with. As you navigate your day-to-day life in the bustling city, you must piece together a mystery involving your patients' pasts, all while coming to grips with the ethical dilemmas of your profession. Solve puzzles, engage in dialogue with colorful characters, and uncover the fate of a missing host body whose heart you've recently transplanted into a patient. With each choice you make, the path of the narrative shifts, leading you deeper into the tangled lives of those who came before you. Will you uncover the truth or will their memories consume your own?
