College students seeking internship certificates found a generous cast of Mary Sues as extras. However, because they stayed up late the first night to revise their graduation thesis, they fell asleep in the car on the way to the set. An inexplicable accident occurred on the way, causing the five of them to enter the real Mary Sue world. At first, they knew nothing about it. They only felt that the people here had a strong sense of belief and no NG. But at night, they discovered that the dimension was really broken, but they had to continue acting to avoid being regarded as aliens. Fortunately, everything so far conformed to their previous script.
