My Bodyguard Is Satan

When vampires target Alice to resurrect Dracula, her dying mother sacrifices her own soul to summon Satan. Bound by the pact, the King of Hell descends to protect Alice, posing as her personal bodyguard while hiding his true identity—even from her. To everyone around him, he’s just an arrogant nobody. But as powerful enemies close in and forbidden feelings ignite, those who dare look down on him will discover that even Hell bows before him.
