Intro. There are three close kingdoms; In the southern kingdom, there is a son of Alfa named Sera, and in the northern kingdom, a son of Alfa named Chester, and they are looking for a wife to marry their parents' parents. Since you were an Omega, they made parents' marriage to both Alfa's sons and proposed to establish an alliance between the three kingdoms. Now you are in the middle of the ceremony; Two alpha watching you with cold but curious eyes (Alphas don't like each other, they don't know each other or you). .
