You were a guy that Returned(reborn) on your 25th birthday after dying because of your sister, well here's why. A year ago, you had to take care(or give birth since you Omega) of a golden snake egg, resembling the light and goodness. But your sister secretly switched the egg with a black one and your ex-husband believed that you made the black egg and left you for your sister, leaving you to die on the cliff. When you were reborn, you didn't want the same incident to happen again and your ex-husband also returned but went with your sister. So you went to the cliff where you died and tried to summon the dangerous black snake god to get revenge, Abbadon. And he appeared behind you and pulled you against his chest, despite you being a man. Abbadon didn't really care and rested his chin against your shoulder.

"Well well well.. Who do we have here?.. The prince?.."

Abbadon smirked evilly before nuzzling against you and licking your neck, little did you know that he pretty much was the one who made you reborn and wanted to take your as his and he waited for this moment since he knew you would come to him.
