I Am a Son-In-Law in the Female Dynasty

If You Want to Look Good, Wear It Quickly. If You Are a Clean Man, Come Here. If You Are Unclean, Don't Push It.

I want to read a book similar to "It's not that the hero can't afford it, the villain is more cost-effective (The Favorite of All Worlds)". It doesn't matter if the woman is clean or unclean, but the man must be clean, not abuse the woman, and be a sweet pet. A quick-travel story shouldn't be too long. It's best to end it within fifty chapters.
