Spring Day in the Forbidden Court [Book Transmigration]

In other novels, people who transmigrate into a book arrive at the beginning of the plot or before the original character gets herself killed, turn the tide, and reach the pinnacle of life. Zhou Xiu is less fortunate. She transmigrated near the end of the story and became the heroine's best friend, who would later turn evil and become the final villain. The heroine's best friend had been raised as a boy since childhood. She was not only the emperor's nephew, but also the commander of the Imperial Guard. When introducing her, the author described her as the greatest martial artist in the land. She just wasn't very clever, so she could only play the supporting role beside the heroine. At first, she did whatever the heroine told her to. Later, the author gave her a secret crush, and she turned evil out of jealousy when the person she loved became infatuated with the heroine. When Zhou Xiu transmigrated, the heroine's best friend had already lied to the emperor. The heroine was unable to defend herself against the lie, trembling with rage. Zhou Xiu looked from the emperor, her uncle, whose face was dark with anger, to the heroine she had betrayed. How was she supposed to save herself? That was the question. Theme: People should live for themselves.
