After Rebirth, My Sister-In-Law and I Exchanged Lives

Palace Fighting and House Fighting + the Heroine Being Seductive or Both the Male and Female Protagonists Are in Beautiful Mental States

I want to read a book similar to "Whose pampering concubine will not seek death?" The male and female protagonists are both in beautiful mental states. It's hard to see them taunting each other directly. Hahaha, it's so cool to watch. The relationship between the male and female protagonists is very sweet. I grinned the whole time and felt that the male protagonist treated the female protagonist like his own cat.
