After I Transmigrated into a Book, I Won the Villain's Heart by Acting Cute

She was a world-renowned traditional Chinese medicine doctor who transmigrated into a book as a cannon-fodder supporting female character. Determined to change the original character's tragic fate, she decided to cling to her villainous older brother's powerful coattails. Little did she know she would fall so deeply for him that she became the apple of his eye. He was originally the legitimate heir to a top-tier wealthy family, but because he had been born with disabled legs, he was abandoned. The Ye family later adopted him, making him her older brother in name. As a major villain, he had hated this younger sister with all his heart. But one day, her personality changed completely, and her sweet-talking and coquettish ways made him unable to resist her.
