Grand Duke of the North

In the 19+ barbaric novel, I possessed the heroine Selene, who married the male protagonist Baras, who is called a murderer, and will live in captivity for the rest of my life!
Although he is a war hero respected by everyone, I was afraid of Baras, who also wakes up with a cruel ‘killing spirit’ when the full moon rises. However, unlike the novel, he does not have a terrible appearance and does not bother me, so I am confused. And this guy… he’s softer and more handsome than I thought?

I bought a woman in order to give birth to an heir, but what is this rabbit-like woman that smells like sweet sugar? If I lock her up today and prevent her from going anywhere, she will be tired, so it would be better to start tomorrow.
A two-way romance full of misunderstandings between a man and a woman who are in love for the first time!
