Don't Get Me Wrong, It's Just About Sleeping

The Male Protagonist Is Very Humble and Loves the Female Protagonist so Much That He Begs Not to Leave (I Want to See Something Super Sadistic)

I want to read a book like "Extremely Humble, I Just Want to Be a Dog by Her Side". He didn't leave even though he was being used. Instead, he talked down to the heroine. He didn't want to see someone using his child to kidnap the heroine.
