In 2047, alien civilization observer Yeshaou was ordered to lurk on the earth. His mission was to select human elite samples through the most cruel elimination mechanism-the Chinese Graduate Entrance Examination. However, this "academic master" from a higher civilization underestimated the perversion of the postgraduate entrance examination. English reading comprehension made him doubt his native language system, political issues forced a philosophical crisis, and the most fatal thing was that the greedy neighbor next door, an intelligence dealer who made a fortune by selling postgraduate entrance examination materials, began to frantically test his true identity. When his identity was about to be exposed and his mission faced failure, Ye Shaou was completely defeated by a human girl in the corner of the library saying, "You are not from Earth, are you?" He decided to go against the laws of the stars and confess his love in the most primitive way. And this love across the galaxy will become the trigger for him to defect from his mother civilization.
