This book should be "The Reborn Female Supporting Character: The Counterattack of the Orphan Queen". After the female protagonist Chu Zhaohua was reborn, she clung onto the male protagonist's golden thigh and finally became the queen. I recommend this book to you. It's a very interesting novel about palace fights. It's full of counterattacks and counterplots. I hope you like this fairy's recommendation. Muah ~😗
