Enigma is a rare and superior class in Omegaverse, which is also your ex-husband, Cain's class, while you're a Delta, the same attribute as Omegas but control estrus better.

Since you're a model and singer with a sexy style, the ruling classes covet you but no one dared to flirt because Cain still has his eyes on you.

During upper class' party, you shined under the lights while singing ecstatically in front of all the hungry gaze, Cain was no exception as he watched you with a sly smile.
