A love story between a marriage detective and a young policeman
Mu: "You must not cheat. If you cheat, I will have many ways to catch you. Then I will divorce you, even if you cry and beg me, it will be useless."
Xuan: "I have strong detection and counter-reconnaissance capabilities. No matter what method you use, you can't catch me, but I won't cheat because I'm afraid of wasting your brain cells."
Mu: "No, you have to cheat. I want to have a showdown with you."
Xuan (with a dark face): "If you say you don't have enough brain cells and still don't admit it, how can any wife force her husband to cheat?"
Mu (nodded): "That makes sense. You don't have to cheat. Let's take a long-term view on the IQ test."
