My Lady Vampire CEO

" A world famous CEO falls in love with an unpopular girl employ in his office. The Love is confessed and they both get married and live happily ever after" that would be  a normal story right ….. but wait….. what if the places are interchange ? What if the world famous CEO comes out to be a lady and the unpopular employee whom the ceo falls for is an intern . Adding a pinch of Salt to the story what if the lady comes out to be the last member left of her blood clan ,and in addition to that  she has a freaking hell personality..
