Which ancient romance novel had a plot where the female protagonist pretended to be the twin brother, the Prince of Yan Country, as a hostage?

A Snail in Joy's Eyes.

😋I recommend the following novel to you: - "Spoiled Concubine: A Guide to Cultivating a Spoiled Concubine" - It's not wrong for a husband to be too bad. - "Tang Shang Huan: The Princess Consort is not to be trifled with." - "The cannon fodder eldest sister dressed as the female lead." - [The foolish king is favored, and the ugly concubine is the queen.] - "Princess Consort, don't play dumb." These were all ancient sayings. The female leads all played dumb, and the plots were different. I hope you like my recommendation, Mwah ~😗

😋I recommend the fake woman to you. The male protagonist was an immortal cultivator, and the female protagonist was a modern woman who had traveled back in time. They were full of house fights, immortal world hegemony, and immortal cultivation adventures. The male protagonist could not leave the female protagonist. I hope you like this fairy's recommendation.

I recommend "The Emperor's Doctor" to you. The novel is about a male protagonist who faces divorce because his daughter has leukemia. His daughter's name is also Xue 'er. The male protagonist transmigrated to another world and became a useless son-in-law. Although it's not an ancient romance, it also has supernatural elements. Perhaps it will suit your taste. I hope you like my recommendation, Mwah~

I recommend 'The First Female Mister Who Traversed in Ancient Times' to you. After the female lead, Xia Ziqing, transmigrated to ancient times, she disguised herself as a man to take the imperial examination in place of her brother. In the end, she became the female teacher of the world's number one academy. In this era where men were superior to women, she wanted to see how a woman's identity could be known in the world, opening up a precedent for women to study in history, and be sung by future generations. At the same time, she was faced with a choice when she met the evil, arrogant, but kind-hearted prince, the gentle, but talented young master, and the cold, but silent, guardian swordsman.

My answer doesn't seem to match the information you provided. Can you provide more background or plot details to help me better understand the story you're describing?

Yes, I recommend "The Prince's Wife Is Making Demons". It's an ancient romance novel. The female lead was a peerless beauty, and she even pretended to be a delicate and soft girl. When facing the male lead's brother, she did not hide her coquettishness. In order to please the female lead, the male lead acted like a cute little lamb in front of her. If you like this kind of novel where the female protagonist acts like a spoiled child, this book will definitely not disappoint you. I hope you like this fairy's recommendation. Muah ~😗

I recommend the following novels to you: "In the Book, There's a Master Who Dotes on You","A Guide to the Female Supporting Character in the Book", and "The Female Supporting Character in the Book Struggles to Survive Every Day". These novels were all ancient romance novels. The female protagonist had transmigrated into the book, and they all involved the survival of the female protagonist after transmigrating. I hope you like this fairy's recommendation. Muah ~😗

I recommend to you,"The Fickle Queen." The female lead of this novel is also called Crescent Moon, and she also has a twin sister. The plot of the novel is also very interesting, so it's definitely worth reading. I hope you like this fairy's recommendation. Muah ~😗
