Prince Etienne de Frederick was born a dominant omega, but in a world where omegas cant become the emperor, he must pretend to be a beta due to the empresss greed. When his childhood friend, Grand Duke Rishar von Eckhart, returns after three years as a war hero, theres no time to share a happy reunion as Rishar is a dominant alpha and his rival in the fight for the throne. The two continue to maintain a precarious relationship until, one day, Etienne has a sudden heat cycle, and Rishar finds out the truth. Etienne de Frederick. You were... an omega?
