Character development time! Give me some interesting questions about my character and I will answer.
She would! Xiaoqiao’s English nickname is something along the lines of “the woman who fights for love, not war”. While others may see ‘love’ as her marriage, I believe it means that she fights for those important to her as a whole. Zhou Yu is an important part of her life, but he is not her entire life. She would battle if it meant she could see or protect those close to her. (Like her sister, for example.)
Another tidbit: She also fights to prove to those around her that she is not useless. She is just as good as anyone else in a fight and refuses to let anyone tell her otherwise.
