Hearing Mei Fei Long's irate tone and remembering that she was an orphan, Xiauyue immediately understood that her cousin Miao Xifei had touched on a taboo subject and she was forced to make a decision.
At this moment she had to choose between stopping Mei thus protecting her cousin or staying on the sidelines allowing Mei Fei Long to do whatever she wanted with her cousin. Xiauyue was already starting to get a headache thinking about the possible consequences of whatever her decision was when by chance her gaze fell on Desmond.
Desmond did not have to say a single word, his gaze said it all, and Xiauyue understood it, she understood that Desmond's passive attitude was not because he did not want to or wasn´t going to intervene but that it was a test for her; he was trying to tell her that she needed to make a decision now.
