Background Digging

"Sir, you called for me?" Ming Guang asked rhetorically, shuffling to the empty seat vacated by previous staff. He sat, straight-backed, ready for questioning. 

"I need all the information you have gathered from the past few days." Captain Mu said immediately, wasting no time with pleasantries. "And I'm not just talking about the kidnappers. I want every bit of information - especially about Miss Li's parents." 

Captain Mu's eyes subconsciously darted to Li Tai Cheng and Li Yue Niang, who were staring disapprovingly at Jingwei drinking wine in the morning, nagging him at how unhealthy it was. 

Jingwei then put down his glass shamefacedly, only for his beloved fiancee to take a swig, much to the despair of her parents. 

"Sir? You suspect they're involved?" Ming Guang asked.

"Who knows?" Captain Mu replied cryptically. "They definitely aren't an ordinary civilian couple. If you believe this, I'll have to demote you."
