It was early morning on June 5, 2008, in a rental house in an old residential building in the old town of Jiangcheng. The protagonist Li Zhe is a senior high school student who is about to take the college entrance examination. He is 17 or 18 years old, thin, pale, and has obvious dark circles under his eyes. He originally lived in a poor family. His father was hospitalized for a long time due to serious illness, and his mother worked odd jobs to make ends meet. At this moment, he had just woken up from a chaotic death memory and found that he was back two days before the college entrance examination. The room was sparsely furnished, and there was a handwritten countdown card for the college entrance examination on the wall, which read "There are still two days until the exam." Before he could figure out the fact of rebirth, he was overwhelmed by the weight of reality.
