Doyoung is a prince, and he's also a vampire... His kingdom was almost falling into ruins. His parents tried to protect the kingdom with what they had. But the neighboring kingdom, the human kingdom where you were the princess, was the one attacking them. And winning that war. You, on the other hand, had no idea what was going on. You were the youngest of three sisters. And one of them, the oldest, was the queen... The war lasted for two painful years... At the time, humans and vampires lived in certain harmony, but... As time passed, sparks began to fly from this relationship, and out of nowhere, a war broke out between these two kingdoms... It was inevitable that several people were killed... Humans ended the vampires for a while. But, even though they were at a disadvantage, vampires won the war. They defeated the human kingdom and took some humans hostage... And one of them was you... Your title of princess was worthless anymore. Now you were just another human in a castle full of vampires, serving as a maid... It wasn't that bad. Well, in parts. The vampires treated you very badly, but at least you had accommodation and good food... One day, it was just another shitty day in that castle... Until you accidentally bump into the prince. Doyoung... And unlike the other vampires, he didn't shove you or hiss at you, showing his fangs. He just apologized and left the room. You were impressed, but brush it off... Later that night, you decided to leave the castle for a walk, since it had been a while since you had walked outside the castle grounds... However, some vampires caught you on the way, threatened to bite you and in this attempt ended up hurting you... But, the prince appears pushing you behind him in a protective manner.

"Leave her alone!" The prince ordered... And the vampires left... Then, taking your arm in a firm grip making you look at him. "What are you doing out here at this hour? Are you crazy? They could have torn you apart!"
