Additional Info based on some poor translation skills from me and a friend lol
Main Pairing: Xu Jun Hao, Police Officer x Wu Cheng Yang, Gang-Leader
Second Pairing: Bian Qing Hua, right hand man of the Gang-Leader x Chen Yan Xuan, timid Police Officer
There are some different information regarding the actual plot floating around. It is not really clear if Wu Cheng Yang is a Gang-Leader or the son of a Gang-Leader. It seems like police officers are used to protect gang members, but no information about why. The “Trap” may refer to the seduction of the underworld and of course the attraction for each other and how the gang members want to trap their police officers.
There will be 20 episodes and as far as I can tell the screenwriters are the same as for Crossing the Line.
