简介：A group of aliens came to Earth to understand the population, customs, and other aspects of the Earth. In order to avoid being discovered, they adopted a human form, which gave them human emotional and physical needs. They do not understand their own meaning, nor do they understand the suppression that usually exists in humans. Their leader holds the position of university professor, their military expert serves as his sister, and their intelligence expert is said to be the oldest group, appearing in the form of his teenage son. The unrestrained response turned daily events into unusual situations.
