Zhou Xu is introverted and slow-tempered, and is always a little reserved when facing unfamiliar environments; Meng Yao is enthusiastic and kind, and warms the people around him like a little sun. By chance, the two walked together and started a fulfilling high school life.
In studies, they supervise each other, learn from each other's strengths, and make progress together in tests and competitions; in life, they listen to each other's worries, share joys and sorrows, and become the most reliable partners. From being polite and unfamiliar at first, to talking about everything, the boys and girls supported each other amidst academic pressure and growing confusion.
The four seasons of the campus flow, the pen writes dreams, and the smile witnesses the companionship. This beautiful feeling between friendship and heartbeat accompanies the two of them as they lose their childishness and grow up, becoming the most precious and exclusive memory in their entire youth.
