Lu Qingfeng obviously wouldn't stand aside watching his woman getting bullied in front of him. Regardless if she had yet to give him a definite answer, he would never allow anyone to talk down to her. He gave Su Xiaofei a glance as if telling her that he would be the one dealing with Cai Lin.
Meanwhile, Cai Lin did not expect that Lu Qingfeng would stand up for Su Xiaofei. Everyone in the academy knew how close these two were, almost as if they were lovers. The only reason he rushed out to confront Su Xiaofei was to force her to apologize to Ye Mingyu.
However, this was the first time that Lu Qingfeng had vocally made a move to defend Su Xiaofei from someone. Some thought that he couldn't be bothered about trifling things that Su Xiaofei could deal with on her own. And it was because he never made any stand to protect Su Xiaofei before that some even assumed that he was merely there as her companion.
