Su Yan and Lin Cishu were classmates in elementary school. When she was in elementary school, Su Yan was originally a quiet and reserved little girl, but Lin Cishu, the girl behind her, was noisy and cheerful. Gradually, the two became familiar with each other and became the best friends in the class, and Su Yan gradually became more cheerful. After graduating from elementary school, the two lost contact because Su Yan went to study abroad. By chance, Su Yan returned to her hometown to attend high school, and unexpectedly reunited with Lin Cishu. Su Yan gradually discovered that her feelings for Lin Cishu had changed from friendship to love, but she did not expose it because she was afraid that the two would not be friends in the future. When she graduated from high school, Su Yan was ready to be brave, but Lin Cishu told her before that they were best friends. Su Yan was disheartened and buried this love in her heart. After going to college, Su Yan fulfilled her wish and became an excellent surgeon. One day in the emergency department, a critically ill patient was sent to the hospital. He was stabbed several times by the kidnappers for rescuing a kidnapped little girl. Su Yan prepared for the operation as usual, but found that the person on the operating table was Lin Cishu whom she had not seen for a long time. Su Yan couldn't calm down for a long time, but she still performed the operation as usual. But in the end, Lin Cishu died of his injuries. Su Yan was distraught and blamed Lin Cishu's death on herself. On the day of the funeral, Lin Cishu's mother handed Su Yan a diary and found that it was Lin Cishu's 17-year secret love diary. From the time the two met in the first grade of elementary school to the day before his death, the initial friendship turned into love. It turned out that on the day of graduation, Lin Cishu was afraid that the two would not be friends after failing to express his love, so he covered his former tenderness with a layer of friendliness. Su Yan burst into tears in front of his tombstone, telling her love over and over again, and eventually suffered from severe delusional disorder, but she always resisted treatment because she could no longer see Lin Cishu after taking the medicine. Lin Cishu's life stopped at the age of 24, and Su Yan was forever trapped on the day Lin Cishu died.
"The most unbearable thing in the world is that Zhuyan bids farewell to mirror flowers and bids tree." Just like this poem, Su Yan couldn't keep Lin Cishu's life, so she had no choice but to say goodbye.
