After Entering the Book, I Drove the Mad Prince Wild with Flirtation

The night she transmigrated into a book, she became a dead piece in Prince Jing's eyes. He was ruthless and possessive, and had long known she was a spy, yet insisted on keeping her by his side.

In the end, this unhinged prince was driven completely mad by her charms.
