King of the Underworld

In my life as a waitress, I, Sephie - an ordinary person - endured the icy glares and insults of customers while trying to earn a living. I believed that this would be my fate forever.
However, one fateful day, the King of the Underworld appeared before me and rescued me from the clutches of the most powerful Mafia boss's son. With his deep blue eyes fixed on mine, he spoke softly: "Sephie... short for Persephone... Queen of the Underworld. At last, I have found you." Confused by his words, I stammered out a question, “P..pardon? What does that mean?”
But he simply smiled at me and brushed my hair away from my face with gentle fingers: "You are safe now.”
Sephie, named for the Queen of the Underworld, Persephone, she's quickly finding out how she's destined to fulfill her namesake's role. Adrik is the King of the Underworld, the boss of all bosses in the city he runs.
She was a seemingly normal girl, with a normal job until it all changed one night when he walked through the front door and her life changed abruptly. Now, she finds herself on the wrong side of powerful men, but under the protection of the most powerful among them.
