What if Silla not only has a faceless king but a queen as well? What if Jin Heung has a twin sister that would rule Silla with him? What if she has been hidden for 12 years but returns not as a woman but a man? And what if she joins Hwarang and falls for the enemy's son?           This Golden Age of Silla will live on to be one of the most scandalous, chaotic, and prosperous time in History.
