Yu Song developed a low fever due to reviewing for the university's final exam, and went to the school infirmary to get medicine after the exam. The doctor asked him to re-measure his temperature, so Yu Song was pulled into the system while he was taking a nap on the bed in the infirmary. After completing the four world line tasks, he was forced to enter the fifth world due to system reasons. In the fifth line, he returned to the first year of high school with Bai Fangshuo, who also signed a contract. Yu Song attacked Bai Fangshuo, but accidentally saw something that shouldn't have appeared at that time. After recognizing Bai Fangshuo, the two left the system and began to interact in real life.
