Yun Shu did not expect that because of a failed stage play, she would become good friends with three girls, Ni Xu'an, Xia Yan, and Huang Xuanyue. They have spent a long time growing up together and firmly believe that their friendship will last forever. However, during a trip, Xu Yunshu accidentally took the wrong suitcase with a strange girl, and the music box with special significance was lost. The friendship between the "cute swan girl group" was thus broken. She had low self-esteem and began to refuse to participate in small group activities; Xia Yan, a beautiful girl who was originally "innocent", became a "bad girl" in the eyes of her classmates because of her past with the "boys who followed her"... Graduation was about to happen, but they drifted apart. Xu Yunshu couldn't help but feel confused - did the nine-year friendship end like this? When graduation really came, parting made them grow up overnight and understand the meaning of friendship. When the resentment was eliminated, they decided to do all the things they had done together and those they had not yet had time to do again... Youth is full of mistakes and misses, but precisely because of youth, no matter how many cracks there are, there is still time to make up for them. There will be so much time in the future that can be used to say goodbye with tears and "Long time no see" with a smile.
