When he was seventeen years old, Xu Zhi was a talented little painter, free and easy, very happy. In order to find inspiration, he came to Yunyi No. 13 Middle School and met the "idiot" Dai Bo'an by chance. The seventeen-year-old Dai Bo'an was like a young poplar tree, steady and polite, silent but not reticent. In the face of isolation and bullying, he thought, if he endures it a little longer, the day will come. , But he always stopped at the age of seventeen, in the midsummer of that year; the seventeen-year-old Zhou Jingluo was a troubled girl who did everything. She was just getting by. Even if she was beaten to death, she would not have thought that she would become a teacher at Yunyi No. 13 Middle School. She thought, if she had not gone to the rooftop that day and witnessed Dai Bo'an's fall, would there have been a different outcome? It seems that at the end, Lin Zhiye, who was only seventeen years old, was so enthusiastic and growing upward.
An "accident" changed the growth trajectory of many people. After many years, can they find the truth hidden back then?
