If you like sweet sadistic novels, I have two here to recommend to you. The first book was "When I See You, My Heart Isn't As Good As I Thought". It was both sadistic and sweet. The male lead was a refined and cold person at first, but because of the appearance of the female lead, he slowly became gentle and loving. The female lead was a brave and strong woman. Although she had experienced many hardships, she still had a happy ending in the end. The second book was "My Time Stops For You." The male and female protagonists were both physically and mentally clean. Although it was a little torturous, it still had a happy ending in the end. I hope you like my recommendation. Muah ~
