Everyone in the school praises Luo Ning as a well-behaved model girl who is obedient, sensible, and has excellent grades. She is a top student who cannot find any faults in the eyes of her teachers and parents. But no one knew that this well-behaved senior high school girl hid the most rebellious secret in her entire youth - she secretly fell in love with Ge Xu, an unruly and problematic senior in the repeat class next door. Ge Xu is the most outrageous person in the school. He skips classes, smokes, and acts recklessly. He is a negative teaching material in the words of the teacher, and is ordered by all parents to stay away from his children. No one knows that this wanton and flamboyant boy decided to repeat his studies last year with high scores in a top university, just to wait for her who failed the college entrance examination. The two carefully concealed their ambiguous ambiguity, sneaking close to each other in the high-pressure high school campus, and tenderly redeeming each other. The school has strict rules, strict inspections by teachers, and is riddled with rumors. The restraint and tolerance of a good girl collides with the paranoid tenderness of a rebellious boy. Misunderstandings are piled up one after another, and the pull and pull is repeated. Luo Ning mistakenly thought that he was being naughty and wasting his time, so he deliberately distanced himself and did not dare to get involved deeply; Ge Xu hid all the truth about the re-reading, silently stayed up late with her studying questions, and bore all the criticism and grievances alone. The youthful bond begins at first meeting and is hidden in the years. Two boys and girls with extreme contrasts, during the chaos of their senior year in high school, unlock a sweet and sadistic love that is forbearing in both directions and running in both directions. All the waiting and paranoia are for the rest of their lives.
