Like a Mama Bear protecting her cub, Ming Xiaoyu protected Su Yanruo. She wouldn't let any guy come close to her. If any guy dared to talk to her, start a conversation or ask her out on a date then she would punch that guy in the face or make him run away in another direction. There were already five boys in the college who got a taste of her wonderful fist and sarcastic mouth on the first day. If Su Yanruo got the title of the 'College Beauty' then, Ming Xiaoyu was called 'Lady Don,' or 'Miss Protector.'
