Looking for Forced Love from Boss Wen (Begging on Your Knees)

I read a novel about a boss many years ago. All I know is that the male protagonist's surname is Leng, and he is a little bit sadistic. I forgot the female protagonist's name, but she is a cute girl. She starts off as a douche. The male protagonist keeps abusing the female protagonist and forces her to make love! I haven't watched it since. I hope I can find it. I want to keep looking.
