Beautiful Sassy Omega.

Axe Noir, omega and second in the line of succession to the throne must marry Erwin Feret, alpha and current heir of the enemy kingdom due to the outbreak of war.

Axe is everything an omega of his time shouldn't be: bold, independent, with strong opinions and total fighting prowess, he is an insolent omega, and that drives Erwin crazy.

Erwin is an alpha raised in a toxic, alphaist environment, adapted to do what he wants, carefree and living his love affairs.

Both as different as they are, they are destined to fall for each other, even if at the beginning they are only driven by desire, they may unknowingly be about to live the greatest love story of all time.

That is, if war and lies don't destroy them first.
