"What's there to be happy about?" said the person, inadvertently.
"Hmm? What did you say? How come you're not happy? Everyone at the Mu Residence is joyous."
"No... I didn't say anything, I'm just feeling a bit unwell. I'll head back first." With that, he put down what he was holding and turned to leave.
Inside the study of the Mu Residence owner, "While we were attending the National Day rally, was there any unusual activity in the residence?" Master Mu asked the person beside him.
"No unusual activity, Sir, just some suspicious individuals." The questioned person was the butler of Mu Residence, the middle-aged man responsible for overseeing all the affairs of the residence. Before leaving, Master Mu entrusted him with the task of secretly investigating the mole within the residence.
"Hmm... Don't alert them yet. Investigate in secret and report back to me if you find anything concrete."
"Yes, Sir."
