The green brick wall of the old alley still bears the height marks of the two people. The "war" between Pei Heqing and Liang Yanni lasted from childhood to high school. He is a duplicitous and sharp-tongued academic who always takes pleasure in teasing her; she is a tough-tongued girl who refuses to admit defeat, often making him speechless. She counterattacks accurately every time, and the sound of bickering between happy enemies runs through the four seasons.
The spring sunshine shines through the camphor leaves on the desks, accompanied by street lights after evening self-study, and comments on each other's mistakes in the wrong question book. Amid the commotion, young feelings quietly grow. It turns out that the agreement between childhood sweethearts is to hide the purest heartbeat in every youthful time.
Intention: Companionship is the longest confession of love.
