The Beautiful CEO's Dragon Guard

He was once the power broker of the underworld!

He was once a devil who struck fear into the hearts of his enemies!

Now, because of a promise, he has returned to the bustling city. He had hoped for a peaceful life, but the woman he loves favors him, his enemies bear a grudge, and powerful factions come knocking one after another like moths to a flame.

To protect her, this time he will return to the sea like a roaming dragon and stand peerless beneath the heavens!
