Fu Rong and Xu Jin overhear how Qi Ce has failed three of his assassination attempts. They both investigate him separately. Fu Rong is interested in him because he is the man who will marry her sister. Meanwhile, Xu Jin enlists Wu Bai Qi to go undercover in a brothel to look into Qi Ce. Fu Rong is there too and instead of investigating she ends up drunk. In her stupor, Fu Rong thinks Xu Jin is her sister and starts spluttering out her love for her. Xu Jin piggybacks her out of the brothel. (Source: cyn-lynn.blogspot.com)
