Lin Ke Yubei is an obedient top student who is loved by his teachers, but Lin Feiyu is a schoolboy who gives teachers headaches. One sits in the front row of the classroom, and the other moves around in the back row. The two worlds apart are often forced to wear "couple costumes," quarrel frequently, and are often mistaken for lovers. Transfer student Fu Junxi is a tall, rich and handsome boy in the eyes of his female classmates, a talkative boy in the eyes of his teachers, and a sultry boy in the eyes of his brothers. He is the only one in the school who dares to wander around without a crew cut. She develops a crush on the sometimes well-behaved and sometimes eccentric Lin Keyu next to her good brother Lin Feiyu, but she always hides her feelings. Transfer student Zuo Yanran accidentally became roommates with Lin Feiyu, and became good sisters with Lin Keyu, but she and Fu Junxi ignored each other. What kind of storm she will bring to Lin Keyu and Lin Feiyu... Youth is full of all kinds of joy, hesitation, and love, but the ending often makes people sigh, but those beautiful things, beautiful memories, and beautiful people are enough to support them through that storm.
