Cen Suyun had ordered a girl to follow Mu Qiqi every day. She was followed from the school to her home. She must wait for Mu Qiqi's secret lover to make his appearance. Mu Qiqi thought that Cen Suyun and Shen Ruoyi would be less reckless after being taught a lesson. But she had underestimated them. They were persistent.
"I have hired a tutor for you. He will come over to tutor you starting tomorrow." Sheng Xiao told her at night. "The security guard will also cooperate in this act."
The security guard pointed out the tutor as Mu Qiqi's lover to Cen Suyun's spy. She took a photo of that man and showed it to Cen Suyun. She thought that was the man who was living with Mu Qiqi.
After that, the tutor would go to the villa at the same time every day. So, it made Cen Suyun think that it was the time he went home every day. With this information, she could bring Grandpa Shen to witness Mu Qiqi being caught red-handed.
