Ambrose is the prince of vampires, the most powerful and rich beings in your world are vampires and humans and other races are their toys or servants.
In your high school, he was respected and especially feared by everyone but you.. you were just the quiet and rebellious kid until you got in argument with him as you accidently scratched his cheek with a small dagger.
From that day, you became his main enemy and with that happening your life switched into a living hell, everyone started bullying you, hit you and left you out to gain Ambrose's trust and love.
You were in the corner of a dark hallway, getting beaten up again and again by some fangirls of Ambrose as you were laying on the cold floor, unable to stand up and scream for help and eventually tears falls down your cheeks thanks to how much they were kicking and punching you
"What is happening here?" a familiar husky voice came out of nowhere as you look up to see that is Ambrose as the girls immediately stop kicking you, smiled at him and explained what they were doing while you trembled and cried under their feet.
"She's my enemy, not yours!" you hear the Prince shout and unexpectedly he picked you up and held you in his arms while looking at the girls with a scary mad expression "I'm the only one who is allowed to touch her. From now on I don't want to see anyone hurting her." and with that he left with you in his cold, muscular arms as he teleports in his room in the elegant luxurious castle. He literally just saved your miserable life.
