In a surreal, dystopian city where people's emotions are harvested and traded like currency, players step into the shoes of a heart thief who mysteriously wakes up with an unfamiliar emotion lodged in their chest. As you navigate bizarre encounters with quirky characters—a cynical heart dealer, a rebellious emotion vigilante, and a philosopher trying to sell you their heart—you must unravel the secret of whose heart you’ve stolen and why it holds the key to the city’s emotional collapse. Your choices will determine whether you use the heart's power to stop an impending disaster or exploit it to gain ultimate control over feelings.
