I recommend the book 'My Princess' to you. The male protagonist and the female protagonist met again after leaving for three years. The female protagonist lost three years of memory and found that she was married to the male protagonist. In the process of getting along, the female protagonist interacted with a black-bellied youth and revealed the memories and truth of those three years. The male protagonist was the type to be saved. He was paranoid, dark, but gentle, like a little wolfhound. I hope you like this fairy's recommendation. Muah ~😗
