Lin Wei, the "Bingshan monitor" who is the number one in the grade, and Jiang Yu, the notorious thorn-headed school bully, are at odds with each other in the smoke of high school competition. He mocked her as a "rules slave" and she denounced him as a "scum of society"; he tore up her weekly duty record and she reported his truancy; he swore that "he would never like nerds", and she swore that "breathing the same air as a bastard would be disgusting" - until a heavy rain locked the two of them in a dark equipment room. Under the soaked school uniform, the boy caught a glimpse of the bruised work scar on her collarbone, and the girl heard him humming the lullaby left by his mother. The Shura field, where they were forced to form a team to prepare for the school anniversary, became a crack through which they could glimpse each other's souls. He went over the wall to buy medicine to keep her from having a high fever all night, and she stayed up late to organize the test sites and fill his desk; he pawned his mother's belongings to pay for her mother's surgery, and she mortgaged his scholarship to save his dying entrepreneurial dream. When Jiang's father's check hit Lin Wei's face, when Tang Zhe's gentle trap came wrapped in a diamond shell, the former enemy was betraying the abyss. Finally it became clear: they were already teammates fighting back to back.
From the confrontation in the corridor to the proposal in the ward, from the pull ring of the can to the wedding ring with the class emblem - "Catch me!" At the graduation prom, Lin Wei's white gauze fell, and Jiang Yu tore his suit and grabbed the safety rope. While the whole school exclaimed, he kissed the bride in his arms and chuckled: "I didn't hold you back on the rooftop, but I caught you this time." Under the stage, Jiang's mother put on a jade bracelet for Lin Wei, Su Qing's daughter jumped up and down clutching her armband, and the elegant bouquet fell into the palm of a strange girl after seven years.
