Forced into marriage by her grandfather with a bride price of eighty-eight thousand, Li Xing'er impulsively grabbed a passerby to register their marriage out of spite, not expecting the other party to be Li Zechen, the anonymous richest man of Yecheng. She stood firm against her patriarchal, toxic grandfather and calculating father, sparing no effort to protect her mother who had endured for years. Li Zechen went from initially holding a testing mindset toward their flash marriage to gradually turning into a tsundere wife-protecting maniac, compounded by a divine mother-in-law's strong assist. Various toxic relatives took turns coming over to find fault and got their faces slapped every time. The two who married first and fell in love later slowly developed genuine feelings from merely getting by together.
