In the second grade of No. 7 Middle School, the academic god Lu Shi'an and the school bully Jiang Du are notoriously bitter enemies.
One is the cold and cool number one in the grade that the teachers hold in their hands, and the other is the thorn-headed demon king who gives the dean a headache. Everyone thought that when they met, sparks would hit the earth, until one night after self-study, someone saw Jiang Du blocking Lu Shi'an on the dark rooftop.
Jiang Du chewed on his cigarette and smiled mischievously: "Good student, the steps of the big question you copied for me last time were wrong, which caused me to be scolded by the math teacher. How to calculate this account?"
Lu Shi'an took the cigarette out of his mouth expressionlessly and put it out, pushing up his glasses: "I'm scolding you because you can even copy the wrong line. I'll give you extra lessons tonight at the same place."
No one knew that in the corner where no one could see, the lonely academic god and the irritable school bully were actually each other's only light. They established a "learning mutual aid group" with only two people in an abandoned music classroom, and communicated using secret codes that only each other could understand. One of them wants to break away from the suffocating native family, and the other wants to escape from the muddy bottom quagmire. They originally agreed to go to Beijing together, until Jiang Du's "murderer" father, who had disappeared for ten years, suddenly appeared. Rumors about his life experience exploded on the campus walls, and Lu Shi'an's qualifications for being escorted to Qingbei were also in danger of being replaced.
In the summer of eighteen years old, the backbones of young people are repeatedly tempered by the weight of reality. When everyone was waiting to see them part ways and turn against each other, Lu Shi'an grabbed the microphone at the swearing-in ceremony and said to the teachers and students in the school and the person who tried to replace him: "Want to change my position? You can. Test the person next to me first."
The spotlight shined on Jiang Du in the corner. He slowly stood up and smiled openly amidst the waves of boos: "The code is still the same?"
Lu Shi'an looked back at him across the sea of people: "The code is still the same."
Intention: In adolescence full of prejudice, through self-salvation and two-way pursuit, break the shackles of the original family and the shackles of external definition, and finally achieve the growth of "1 1>2".
