Hei Chai began her secret surveillance plan; she chose to personally follow Hu Zefan because she knew him well.
Hu Zefan's company was located in a 5A office building just two streets away from There is a Bar. Hei Chai wanted to take a look, but fearing discovery by Hu Zefan, she first rented a hotel room opposite the office building and secretly observed for two days with a telescope.
On the third day, she made an outfit identical to the cleaners in his company and infiltrated his office.
Carrying a bucket and mop, she arrived outside the President's office on the top floor, looked around to ensure no one was present, and quietly approached the door, intending to eavesdrop on some useful information.
Coincidentally, the door was not fully closed. Through the ajar door, she glimpsed a disgraceful scene inside.
Hu Zefan sat on an office chair, with a young girl who looked like a secretary sitting on his lap. The two were flirting intimately, clothes disheveled.
