I Died Saving Someone, Then Returned to Age Eighteen with a System

The protagonist, Lin Yi, saves a little girl on the road just before she is hit by a heavy truck. After losing consciousness, he wakes to find he has transmigrated into the TV series "With You", where he has become a high school graduate who has just taken the college entrance exam and is about to enroll at Southern Media University (Southern Media College). He is bound to a Sign-in System that issues random tasks. Completing them earns sign-in points, which can be used to buy various items he has unlocked through sign-ins, such as money, skill books, novel outlines, and movie scripts. His first task requires him to apply to Southern Media University’s TV Photography program and join the class with Lu Qiaochuan, Zhong Bai, and the others.

(This novel is based on the TV series "With You", but its plot does not follow the series exactly and will make some minor changes to the original storyline.)
