What surprised him most this time was that he actually found that Rao Tiansong’s lawyer Du Housheng (played by Ekin Cheng) had a wife named Amy (played by Angelica Lee), who looked very much like his girlfriend who disappeared ten years ago. All this made him devote a lot of effort to the investigation of the case. However, in addition to Sun, there is also killer Qu who is interested in this case. They each have their own concerns, and they are cautious step by step, pulling and fighting in the intricate relationships and events.
