Maria, a PhD in Botany living in the 21st century high civilization world, died suddenly because of staying up late to write a paper and traveled to another world, a place seems to be very similar to the medieval environment she learned in history books. The difference is that the man who half-robbed and half-coaxed her back to the castle always forcefully enters her room on the night of the full moon... Occasionally when he cums, a pair of silver-white fluffy ears will appear on his head, just like a big dog. Fortunately, she has knowledge of the high civilization world, so she can live well even in a world similar to the Dark Middle Ages with stinking and food shortages. Simon de Montfort was born in the Montfort, the noble family with extensive territory and prominent status. Although he is the second son, he has wealth and power that ordinary people can't imagine since birth. Especially after his father knew that he inherited the blood of the original wolf king, he paid more attention to him. In order to avoid disputes with his brother and make his mother sad, Simon decided to give up his father's title in Gallia and go to Iberia to inherit his grandmother's land. Simon was very glad that he came to Iberia, because when he was 20 years old, he found his Luna in the forest. All content of this novel is purely fictional, please do not take it as reality.
