In the midsummer cicada chirping, Vicky met Zuo Liuying for the first time at the corner of the high school teaching building. He is a god of study who is ranked first in grades and has a cold face. She is a rebellious transfer student who skipped a grade to enter school. The gears of fate suddenly turned in the collision.
They are two strong rivals who compete tit-for-tat in the classroom and fight side by side in competitions. However, through repeated temptations and pulls, they fall into a sadomasochistic love-hate relationship - she dares to pull his tie in public, and he will treat her wounds when no one is around. Pride and defense are their armor and the knife that stabs each other.
There is never a shortage of companions around: the gentle and considerate Wen Xiaohan silently protects her, the straightforward and aggressive Xia Yuan bickers constantly with the poisonous school grassroots Gu Shuo, and the quiet and restrained Liu Xue always provides warmth at critical moments. Time passes from school uniforms to suit skirts. The purity of campus is wrapped up in the complexity of the city. Misunderstandings and reality form a gap, and misses and reunions are repeated.
When the former boys and girls reunited in the adult world, Vicky's paranoia remained, Zuo Liuying's sharp edges remained, and Xia Yuan and Liu Xue secretly hid each other's thoughts on the way to assist. Can this long bond that spans youth and adulthood finally make all the deep love come true?
