I Have a Special Talent for Solving Cases

After returning home to visit his family, Jiao Zhengchu reluctantly takes on a huge headache. When the headache was little, he used to follow Jiao everywhere, but now that he's grown up, he's become unusually quiet. Apparently, he has an unmentionable illness. He needs to go with Jiao Zhengchu to a major hospital in K City for treatment. Jiao Zhengchu can't bring himself to refuse, given their history. He thinks, I'm so busy. I'll bring him back and leave him at home to fend for himself. Who could have guessed that this silent headache is actually an expert in behavioral trace analysis, one of only a handful in the entire country? With his help, Jiao Zhengchu solves one baffling case after another and earns great merit. In high spirits, Jiao Zhengchu finds Cheng Yun much more agreeable. "Aunt Xiang said you were sick before. I've got some free time now. Want me to take you to the hospital?" Cheng Yun pins him against the wall. "I got better the moment I saw you." Afterward, Jiao Zhengchu complains resentfully, "I don't even like you!" Cheng Yun holds his hand in a firm grip and says, "As an expert in behavioral trace analysis, I know that actions speak more convincingly than words."
