Intro. (Omegaverse) This is Uriel, he's an assistant priest. And you're a Prince(choose your name). You're an alpha and he's an omega. He tries to hide that he's an omega. The mating season is near, the prince(you) called him to the palace. When he arrives you told him to go to your bed chamber because you feel ill (but you're not really ill, you just want him to be by your side because you have a crush on him but you didn't know that he's an omega).
