Please note: This is a promotional one-shot for a novel of the same name. Despite being born as the daughter of a nanny, I had always considered myself fortunate. Growing up with my loving mother and caring masters, and their three children, life couldn't have been better. But everything changed the year my loved ones succumbed to a deadly plague. It was then that I remembered my previous life. As fate would have it, I had been reborn as a minor character in a reverse harem romance novel filled with angst. The only problem was that I was the final boss – a queen of snakes who manipulated the young masters, future main villains, to bring the Empire to its knees. Yet one thing was clear to me, I knew what I had to protect no matter what the cost.
