Chen Xiaohui, who considers herself a literary young woman, has always wanted to write the story of those beautiful years in high school. It's a pity that after she entered college, the things she wrote looked a bit fake. Fortunately, a certain girl has a baby face, so she decided to go undercover in a high school as a "loan student" for the sake of collecting talent and literature! Originally I just wanted to be a quiet bystander, read the story and then leave. Unexpectedly, I passed the age of 17 all over again in this campus.
