The day before her younger sister Xiao Xi's wedding, the older sisters Xiao Dong and Xiao Nan both returned to their parents' home. Xiao Dong carefully helped Xiao Xi get dressed, while Xiao Nan presented the wedding gift she had prepared for Xiao Xi. Xiao Nan apologetically mentioned that due to accompanying her husband on a business trip, she wouldn't be able to attend Xiao Xi's wedding. This angered Xiao Dong, who felt that Xiao Nan was always intimidated by her in-laws and rarely came back home, and now couldn't even attend Xiao Xi's wedding, which seemed too extreme. An argument erupted between Xiao Dong and Xiao Nan, growing increasingly intense until Xiao Xi intervened and stopped them, thus quelling the conflict.
