An Yan, from Grade 1 (3) of Xinghua Middle School, is an ordinary girl who is overwhelmed by the crowd, but she secretly hides the dazzling Lin Shuoyu in her heart - he is the city's number one scholar, a competitive expert, and the flower of the high mountains in everyone's eyes, but he also quietly falls on her with gentleness when no one is around.
From the meticulous markings on the homework book to the wrong question book sent by Maoxue, ambiguity grew among the fallen pistils of the locust flowers, but was washed away by a misunderstanding. Misses during branching out and sudden bolts from the blue in the hospital turned the belated confession into a fragile dream. Lin Shuoyu left with the secret of congenital heart disease, and An Yan was admitted to Tsinghua University with a promise, but in the cold winter of his sophomore year, he was dragged into darkness by the same disease.
Their love stopped in the unseen first snow and the unsent necklace, sealing their regrets forever in that April with falling pistils.
Concept: The unfinished first snowfall, the unsent necklace, and the unfinished university they went to together. These unfinished agreements have become the footnotes of their love. They also reflect the truth that "not all likes have an ending" in youth, making regret the most profound mark of youth.
