Tang Xi looked at Xiao Jing speechlessly as she said, "Please don't be so childish, Brother! Ning Ke just asked me a math problem today and I helped him solve it. He thought I was as smart as he was, so we left the school together. That's all."
Ning Yan jumped to his feet upon hearing her words. "You solved a math problem for Ning Ke?"
"Is there anything wrong with that?" Tang Xi looked at him, puzzled. She solved a math problem for someone. What was wrong with it?
He Wanyi looked at Tang Xi in surprise and then at Ning Yan. "Has Little Ning Ke asked you to help him with math problems before?"
Ning Yan spread his hands and shook his head as he said, "He said I was not well educated enough to teach him, and that he might as well study himself."
He Wanzhou blew a whistle and looked at the vigilant Xiao Sa and Xiao Jing. "You'd better keep an eye on Rourou 24 hours a day, or else your beautiful sister's heart will be stolen by Ning Ke sooner or later."
