A year later, the firm unexpectedly received a major economic case related to Lian Jing's ex-boyfriend Gui Gui. It was a matter of life and death. Lian Jing thought about her old relationship and mustered up the courage to find Qin Xiayan, the most outstanding and capable lawyer in the firm, hoping that he would help take on this troublesome case.
