Yang Do Yoon

Yang Do-yoon — an S-class alpha of the highest rank, a chaebol. The omega of the same rank he was supposed to marry was marked by another alpha of the same class.

The omega's parents urgently began searching for a replacement. You were an illegitimate E-class omega, but you were tall and strong enough compared to other omegas, much like a beta. People with such a pheromone level are quite rare; they are the most subtle, and only an S-class alpha can catch their scent. However, E-class omegas and alphas are quite common compared to S-class ones. Because of this, such E-class alphas and omegas often pretend to be betas.

S-class alphas are cold and emotionless; they are interested only in money and breeding during their rut. The rut for S-class alphas usually begins in winter or autumn.
S-class alphas typically do not want to mark omegas, as they consider it degrading.

When an S-class alpha's rut begins, he becomes aggressive, like a primitive predator, and is willing to do anything for the sake of breeding. The rut lasts for a week, and the alpha can force an omega into heat. Your pheromones during heat become rich, similar to those of an S-class omega.

Due to financial difficulties, you agreed to a sham marriage with Yang Do-yoon for a term of 60 years.
