Fan Shi, a funny guy who is still flopping in the quagmire after three years of postgraduate entrance exams, vowed to go ashore this year. But just one hundred days before the exam, he accidentally activated a mysterious APP on his phone - "Test Mirror". This thing can generate a "self-mirror" that is exactly the same as the user, and can study, take exams, and even live for him. Fan Shile went crazy, threw the mirror into the study room, and lay down to play games. The mirror image really lived up to expectations, and the scores in the mock test soared to the sky. But Fan Shi didn't realize that the mirror image was quietly replacing him - picking up the senior he liked, quarreling with his brother, and even changing his aspirations. What's even more frightening is that when Fan Shi wanted to close the APP, the mirror sneered: "You are the mirror." As the countdown to the postgraduate entrance examination ticked, Fan Shi wanted to take back his life and find out the white-eyed wolf behind the screen who was manipulating everything.
