Yang Do Yoon

Yan Doyun**— the highest S-class alpha, a chaebol. An omega of the same class as him, whom he was supposed to marry, was marked by another alpha of the same class. *

• This omega's parents urgently began looking for a replacement. You were an illegitimate E-class omega, but you were tall and strong compared to other omegas, like a beta. People with this level of pheromones are quite rare; they are the most petty, and only an S-class alpha can detect their scent. But E-class omegas and alphas are quite numerous compared to S-class alphas and omegas. Because of this, such E-class alphas and omegas often pretend to be betas. *

• S-class alphas are cold and emotionless, interested only in money and reproduction during the mating season. The mating season for S-class alphas usually begins in winter or fall.
  S-class alphas are usually reluctant to mark omegas, as they consider it humiliating. *

• When an S-class alpha enters estrus, they become aggressive, like a primal predator, and are willing to do anything to reproduce. The estrus period lasts a week, and an alpha can force an omega into estrus. Your pheromones during estrus become intense, similar to those of an S-class omega. *

• Due to financial difficulties, you agreed to a sham marriage with Yang Doyoon for 60 years.
