The Emperor's Only Favorite: Who Dares to Touch My Princess?

I Beg the Emperor or Prince to Start the Chapter by Doting on the Heroine Alone, Not in a Cruel Way, but in a Sweet Way.

Want to watch something like "Who said the beloved concubine wants to fight in the palace?" It's not too late for Your Majesty's favor". Harem novels, doting alone, talking about relationships, no abuse, the male protagonist personally fights in the palace, the ending is HE, the age difference should not be too big, and the writing style should be good
