I Became the Tutor to the Wolf Duke

Miana, a female fraudster surviving in the slums, sneaks into a prestigious ducal house by posing as a missing noble lady. However, her assignment goes far beyond pretending to be high society. She is tasked with educating a beastlike knight who knows nothing of human speech or society. Raised by wolves, Arthur is completely untameable and trusts no one. Yet for some reason, he opens his heart only to Miana, gradually transforming into a man who craves her alone.
