The Three Vampire Brothers

"I'm Jay the CEO of this company" he said with a cold look

"I'm Sunghoon the Second hand of Jay" he said in soft tone but dangerous inside and you didn't even notice it

"I'm Jake I will support you until you have mastered the company" he said with a smile

They are the Park brothers, they are vampires but no one knows about it, You entered the company as Jay's secretary you got hired since you are experienced as secretary
