There is a Ghost in Office [Film and TV Commentary]

This is a movie about office ghost stories. Newcomer Pat (played by Karen Mok) just came to work in a company in this building and met his ex-boyfriend Ken (played by Feng Delun). The two chatted for a while, and then Pat took the elevator back to the company. There was only a woman in white in the elevator. She squatted on the ground and kept saying "I'm sorry". Pat found it very strange. Colleagues said it might be caused by the upcoming Ghost Festival... Pat found Connie, the secretary of the company next door, talking to the person in the last row in the bathroom, and didn't pay attention at the time. Then there was a sudden scream in the women's restroom. When everyone arrived, Connie had hanged herself in the restroom with a strange smile on her face. Ken also saw the woman in white in the lobby, and there was a woman in red next to her. The woman in red told him that the woman in white was a ghost and was forcing her to jump off the building...
