In a world where emotions take physical form as sentient colorful creatures, you, the protagonist, are a curator of the Great Emotion Museum. One day, a special heart—a being of pure empathy—goes missing, plunging the world into chaos as emotions run wild, causing unpredictable feelings in everyone. Your mission is to trace clues, interact with whimsical manifestations of feelings like Joy, Anger, and Sorrow, and navigate a society where love is currency and sadness can be weaponized. With each turn, make choices that affect your relationships with these characters, your own emotional state, and ultimately, the fate of the heart you seek.
