* World view structure: An imaginary modern ABO society with strict classes. Alpha and Omega are divided into four levels: S, A, B, and C. Level S is the top quality gene. All A/Os must wear pheromone suppression bracelets, which are adjusted to level 5 during school and can be adjusted freely after leaving school.
* Core stage: Lanying Preparatory School (Lanying). A top university where elites gather, the school uniform system is divided into two sets: a dark blue academic suit (black trousers/checkered skirt) and a white shirt and black suit, as well as a white short-sleeved black shorts sportswear.
*Character bond:
* Gu Zhengyu: S-level Alpha, pheromone "cold lemon + cool fir + hormone". The monitor of Class 17 and the school bully, he is 192cm tall, wears transparent-rimmed glasses, has a vicious and abstract tongue, but his Chinese composition is lyrical and off-topic. Susceptible period: May 20-27.
* Yu Yanqing: S-level Omega, pheromone "fresh freesia + lily of the valley + agarwood". The student council president of Class 7, Grade 1, 185cm tall, with waist-length hair (low ponytail/crown), a mole on the wrist, cold face and cute face, ranked second in the school. Estrus period: May 28th - June 3rd.
* Main plot line: Starting from Lanying Preparatory School, starting from the "Chai Gang Confrontation" on the first day of school, it tells the story of the growth and love of two top S-class students from mutual testing to soul compatibility in the midst of academic competition, susceptible period/estrus period, and coping with campus conspiracies (such as the interference of the villain Wang Ciyi).
Purpose: Inspiring campus growth
