He found out that he is in a world similar to our own with a timeline akin to early twentieth century.

Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.

Richard, who was born with a broken body, thought that this medieval world was outrageous enough, with knights, dragons, witches, and giant beasts.But he didn’t expect to meet Cinderella right after gaining territory. Her 1.8-meter-long legs were so charming that they could crush people to death.It turned out that this was a fairy tale world, or a dark fairy tale.Without saying anything, Master Richard directly helped Cinderella fill up her puffs.Wait, why does the system prompt that Cinderella is a witch? Or a yandere?The 36D dangerous Little Red Riding Hood, the white and tender Snow White, and the long-sleeping Sleeping Beauty are all witches.Different witches can bring different benefits to the lord Richard.Yeah!The master is going to overthrow the world, establish an empire, collect witches, and fill up!

Annabelle Asra:“Wait!” He commanded, hope surged within me. Maybe he will change his mind, but his expression turned icy, and my heart sank as I understood he had no intention of doing so.“I will never allow you to live a normal life, even if the Crimson Moon has shown you mercy, Annabelle. I will make your existence a living nightmare for what you did to my sister.”As I pondered his plans for me once I was no longer part of his tribe, he seized my throat, and his fangs pierced my neck. The pain was unbearable as he marked me. The agony I endured was nothing compared to the torment his mark would bring.Anger, resentment, and bitterness consumed me. A mark typically signifies acceptance and protection, but in my case, it signified the opposite.Betrayed by the Alpha's fiancée, Kari, I was sentenced to death but spared by the Crimson Moon, only to be exiled and marked by my ruthless Alpha, Zachary Ziglar.After surviving and joining a new pack, I discovered I was pregnant without remembering who I had been with. But why did my pup bear a striking resemblance to my tormentor?
