I think it will be the case of child mixup, our yun babi will be the daughter of si family and that pretentious si wen something is definitely that xiang xuiqin's daughter. They're both alike
Argh! Translator and editor, get it right. The family name is just "Si," not "Sijia." Sijia is "Si Family."đ Note that the father is Si Jingting and the daughter is Si Wenxuan.
