The Happiness Mystery of K Star People

In "The Mystery of K-People's Happiness," it is narrated that the K-people, a technologically advanced civilization who can survive without eating, drinking, procreating, or working, felt that their lives lacked only happiness. Thus, they dispatched scientists "Big C," "Medium B," and "Little A" to Earth to search for the "happiness element." Ultimately, in the world's most densely populated casino city, they uncovered the mystery of happiness: happiness is not having everything, but having something to strive for.
