Synopsis of Bad Sister Divorce League

Huang Ershan (Chen Yihan) is a professional astrologer, who almost regards the constellation as the principle of life. When he learned that his younger brother (Cheney Chen) in North Korea was about to have a wedding, and the bride was the most unsuitable person on the astrolabe, he went directly to Busan to ruin the wedding. On the plane, Huang Ershan, who was drunk, told her neighbors about her worries and planned Park Junhao (Jin-hee Ji). Only after landing did she find out that Park Junhao was the father of her brother's fiancee. They formed a temporary alliance to break up a marriage, but they gradually got along well.
