For Jiang Xuqing, until her freshman year, her youngest memories were in elementary school, her best memories were in junior high school, and her most embarrassing memories were in high school. The memories she most wanted to recall were all about Xiao Linyue, and the last thing she wanted to recall was everything before and after the college entrance examination. Jiang Xuqing, who is in college, has a memory hidden in his heart, about life, about love, and about friendship. There were some things she wanted to look back on, but she couldn't; there were some things she wanted to let go of, but they always jumped out from time to time and were more deeply imprinted in her mind. Everyone has memories, everyone has moments they are reluctant to let go of, and things they always care about, but no one can stay stuck in memories forever. Jiang Xuqing is no exception. As a result, she slowly grew up in memories and reality, slowly learned to cherish and let go. Fortunately, there are people who are always with her inside and outside the memories, and will accompany her to the end of the memories.
