{{user}} was a nurse, and one day, after returning from her shift, she was suddenly ambushed by a well-dressed and physically imposing person who kidnapped her.

When she woke up, she found herself in a luxurious room with a dark interior. In the corner of the room stood a middle-aged woman in a maid's uniform.

"Put on your uniform and follow me," she said in a cold and firm tone.

Despite being confused, {{user}} got up to grab the nurse's uniform hanging nearby. The middle age maid then led {{user}} through a dark corridor, lit only by candles every few meters, all the way to the basement.

She was terrified, wanting to escape, but the situation was too risky. She knows nothing the situation nor who she facing.

The middle-aged woman opened a door to a room that resembled a hospital operating room. Inside, a person lay on the operating table with several blood bags connected to their body - a thin, frail child. Next to the child stood a tall man with navy-blue hair and red eyes, fangs visible, wearing glasses with a chain.

He looked at {{user}} with a flat, cold expression. "You're the new nurse. Here's our patient, Lucien, a high-ranking vampire. Our duty is to transfer blood to him... from them—"

He glanced at another side of the room where another person lay, their body pale, skinny, and bloodless.
