Xun's younger brother, Lisa, who is a neat freak, fell into the routine of Zhenmei Plastic Surgery Hospital and had to keep going in and out of Zhenmei Plastic Surgery Hospital. Xun owed a huge debt for his younger brother's plastic surgery and was threatened by Dean Qi to kill for her. But then the dean actually killed Xun's younger brother to escape.
As Xun worked as a cleaner in the hospital, he regularly went to 14 to clean up the garbage every day, thus discovering the secret "Hello cabinet" of the dean and the murder plan of the dean. Quan Xun killed the dean, and then transported the dean's body to three days ago with a Hello cabinet, trying to change the development of the story line to save his younger brother, and at the same time disturbing everyone's investigation direction and getting himself out.
