Derrick ushers Yuyang into a small room in the shopping mall. He returns her phone and gives her a small teddy bear as a token of appreciation. Meantime, Junyan worries about the missing Yuyang. It is Julie’s mother who has allowed Haifeng to have Julie’s handphone. Qingxiong remarks that the teddy bear might have been tampered with. Close inspection turns up nothing. It does not occur to them that Yuyang’s handphone is now bugged. At a hawker centre, Qingxiong notices the decorations on the ceiling. It dawns on him that the murderer could have used a fishing line to pull a rope to the rooftop. Indeed, Junyan finds evidence suggesting this. Haifeng downloads the video clip in Julie’s handphone. It leads them to the murderer. Pacai (Li Wenhai)’s gestures reminds Xiulian of Musen, her late husband's friend. Musen was a good friend of Deliang’s. Xiulian recalls the last phone call she had with Deliang before he died. One night, while Xiulian is closing up the dance school, a mystery person looks out for an opportunity to harm her. At this moment, Yuyang is walking to the dance school. She receives a phone call, and makes it seem as if she is about to turn around and leave.
