The Young Master of a Tycoon Family Willingly Becomes a Live-In Son-in-Law

The heroine of this book is very well written, she is not a virgin at all, she is not kidnapped by morality, she trusts her husband. It's great that the male protagonist shows his abilities when the female protagonist needs help and doesn't hide his identity from the female protagonist. I also like the fact that the male and female protagonists are single-minded in their relationship.
