The Frail Young Lady's Wolfish Maid

Any Palace-Intrigue Stories Where the Male Lead Takes Care of Everything for the Female Lead?

I want something like The Night Before the Ungrateful Little Sister Enters the Palace, the Favorite Consort Is Reborn. After the female lead enters the palace, I want the male lead to love only her. It'd be best if he seems sweet on the outside but is dark inside. I really love that type!! A story about an emperor and his favorite consort, or an emperor and empress!
