Yin Yiyi has been a little menace since childhood. First she made the chubby boy next door cry, then, after moving, she threatened the girl next door into covering for her while she sneaked off to an internet cafe. Now she’s in high school, at the age when you’re young and free to do whatever you want. She brazenly breaks the rules, bringing her phone to school and even calling her dad right in front of the dean. The dean can only wait respectfully for her to finish. After all, her dad is the principal. He can’t do much about it either. She’s his only precious daughter, and if he doesn’t indulge her, she’ll tell on him, and his wife will divorce him. What a predicament. What can he do? As the saying goes, fight fire with fire. If he can’t handle her, he’ll just have to find someone who can cause even more trouble.
