But instead of a grand rebirth as a queen of darkness, she's reincarnated as something far more mundane—a secretary. Rather than despair, Lilith finds this new life amusing.

But when people push her too far, the devil within still comes out to play.When a creep in the office dares to look at her the wrong way, she calmly fixes her gaze on him. “You keep staring like that, and I'll show you what a broken wrist feels like.” The man quickly scurries away, leaving Lilith with a satisfied smirk.Even the rich, entitled girl from accounting isn't safe from her wrath. “You think you can push me around just because you've got money?

Don't test me.” She says this with a calm smile, her eyes glinting dangerously.The day continued like that—stopping creeps in their tracks, putting rude heiresses in their place, and being the flawless secretary she intended to be. But, of course, her boss—the CEO—had his eyes on her, more curious than ever. And while the entire office might fear her or wonder about her, she remained blissfully indifferent. This was fun. And she wasn't here to impress anyone but herself.Who knew being a secretary could be so... interesting?
