A novel about campus counterattack and rebirth. When she wakes up, she returns to the age of sixteen and rewinds her life - the yard in Moli Hutong is still there, her grandfather is still alive, the boy she likes is showing off, and he will be punished for being late... Jian Xiaozhi returns to Moli Hutong for the last time, returns to the yard she sold, and reminisces about the past. He walked to the familiar grandpa's room, opened the familiar cabinet, and took out his diary from inside. The diary was written solidly, with records basically every day. Although it was just a few sentences, it quickly made Jian Xiaozhi fall into the old days. Suddenly I heard the door opening behind me. Jian Xiaozhi turned around and saw his grandfather, who should have been buried completely, now standing at the door in high spirits, with his hands on his hips. "What time is it! You haven't gone to school yet!!" Jian Xiaozhi was shocked, horrified, and stunned in disbelief. Although none of this made sense, she was sixteen again...
