Reflections of a Distant Echo Chapter 17

Omega's pheromones are different from alpha's and cannot control their concentration.

But Ethan Xu seldom smells his own pheromones.

Twenty years ago, the ABO gender ratio reached a 100-year low of 3:5:2. The sharp decline in the omega population made them begin to seek gender rights for themselves. Pheromone blockers were born at that time. They can quickly block omega pheromones in a short period of time, preventing alphas from passively estrus caused by omega pheromones, and truly transforming omegas from passive courtship to active choice, finally achieving true gender equality.

Every omega will use pheromone blockers after differentiation is completed until they are temporarily marked in a romantic relationship or permanently marked when they enter the marriage hall.

Omegas who do not use pheromone blockers are generally considered to be boldly courting.
