(Originally titled "Agent Yi Leng") The chef of Yumei Restaurant, Huang Pihu, is an oily and sleazy middle-aged man who enjoys drinking, smoking, and fiddling with trinkets. He even has a habit of following female students, making him seem utterly unremarkable. However, no one knows that his true identity is the legendary male idol in the hearts of countless women—a retired secret agent, Yi Leng. Now, he hides in the bustling city, living a quiet life for one purpose: to secretly protect the daughter who no longer recognizes him.
