Is there a person like that who makes you brood throughout your entire youth? Is there such a group of people who can dispel the loneliness of youth and hold up a clear sky? One mistake can lead to a lifetime. Then, there are the emotions that spread over time. Only in the middle of the night when no one is around, in a light yellow diary, under the warm yellow light of a small orange lamp, will an overly quiet girl reveal her secret thoughts without reservation, waiting for the golden unicorn in her heart under the cold window. From window to window, from first quarter moon to last quarter moon, every cloud remains unaccounted for. The golden unicorn was raised internally and grew into shape. She was born into a graceful girl, and the unicorn in her heart was also reborn into silvery white. Lu Ling is not Yang Guo. Lin Qingcheng may not be Xiao Longnu or Guo Xiang. Her reflex arc has always been very long. When she looked back, she realized that her youth was not only a song of separation from a secret love, but also the memories of a group of people. Key high schools are actually a pyramid, with three classes: top students, bad students, and bad students. No matter what kind of people they are, they all have their youth stories. There are stories about academic overachievers, and there are also stories about academic bastards. Time has passed and circumstances have changed, and the gap has passed. Southern girl Lin Qingcheng has seen the cherry blossom rain in April. Who can accompany her to wait for the miracle in December and watch the snow in the north?
