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

She was once an internationally renowned top practitioner of traditional Chinese medicine. After transmigrating into a book as a cannon-fodder supporting female character, she resolved to change the original character's tragic fate and cling to the villainous elder brother's powerful backing. Who knew she would get so deeply entangled with him that she became the apple of his eye?

He was born into the direct line of a top aristocratic family, but was abandoned because he had been disabled in both legs since birth. Later, the Ye family adopted him, making him her elder brother in name only. A powerful villain who had hated this little sister with all his heart, he never expected that one day her personality would change completely and her coquettish ways would leave him unable to resist her.
