I think he meant Beta women cause that’s probably all Kyungsoo had been around since he’s a lot a beta.
In ABO, the physical strength of men and women conform to the 'normal standard'. Alphas are superior due to their pheromones. However, male and female omegas alike are pitifully weak.
Of course, there will be exceptions and there will be a sickly alpha, or an alpha born with weak pheromones. Or a muscular omega or an omega born with superior pheromones (like Chowon. But because he's an omega, despite having strong pheromones, it remains that he is weaker than even the average woman).
"Weaker than most women"? Wtf are alpha women also weak?? And he is an omega so isn't is supposed to be weaker than alphas and betas?
