### Core settings of the novel
- **World view**: In modern ABO, society has strict divisions into gender classes. Alpha is dominant, Beta is mediocre, and Omega is regarded as a precious reproductive resource but lacks the ability to protect itself.
- **Protagonist Setting**:
- **Shou (Lin Yu)**: An S-class Omega in top disguise as Beta. He looks cold and ascetic, but in fact he is injected with high-concentration inhibitors for a long time in order to avoid family marriage and the "humiliation of estrus", and disguises himself as a Beta to sneak into the Alpha Military Academy.
- **Gong (Jiang Wang)**: recognized by the whole school as the crazy school boy and the top Alpha. He has a violent and moody personality, possesses extremely rare "Dark Sentinel" level pheromones, is allergic to all Omegas, and only has a morbid desire for Lin Yu's disguised scent (actually suppressed top-level Omega pheromones).
- **Core Conflict**: Lin Yu's inhibitor failed, and the estrus period unexpectedly came during closed training. Jiang Wan blocked Lin Yu in the equipment room when he was in a violent state during the susceptible period. He wanted to commit violence, but found that this "Beta" pheromone could soothe his mania.
- **Reversal Highlights**: Not the traditional A marked O. At the moment when Jiang Wan was about to lose control and bite him, Lin Yu turned against the enemy and used a special inducer to pull Jiang Wan into the spiritual abyss, completing Reverse Marking, causing Jiang Wan to become physiologically dependent on him from then on.
- **Creative Highlights**: Breaking the stereotype of "Alpha's absolute dominance" and emphasizing the game of mental power and will.
Purpose: I want to tell everyone not to trust the people around you easily, but only in the workplace. I also want to tell everyone that love has nothing to do with gender, only what the heart wants.
