Since both parents could not be reached, the first person the police contacted was, of course, the nanny. But the nanny couldn't give any details. After Su Lin started going to the chess academy, she did not have to come regularly to babysit. On that day when Su Lin was alone, the nanny wasn't supposed to come anyway. But she did know the name of the company where Mei Lin worked. After this information was verified by the police, they called up Mei Lin's employer. From what her colleagues said, she left alone at her usual time the day before. They weren't sure where she went after, but assumed she headed for home as usual. Following the CCTV's trails and several other witness testimonies, inspector Wang's colleagues found that Mei Lin had met with her husband, Weihan Lin, after work the previous day.
The meeting location had been a coffee shop near her workplace. It appeared that Weihan had been waiting there to catch her after work. The barista only remembered the young couple because he had been struck by how unhappy they looked. They had ordered drinks, but left without drinking any of it. The woman had appeared to be high-strung and in a huff, and the man downcast. After some routine questions, Inspector Wang got his juniors to send the CCTV footage from the coffee shop. He really wanted to take a good look at this irresponsible couple and see what they busied themselves with.
However, once Inspector Wang started watching the video, his expression became increasingly grievous. Of course, there was nothing to "see" in the video itself. Rather, he was reading lips. Although the information was choppy because the couple's bodies were frequently obscured from the camera by people passing by their table, it was enough. Enough to figure out that Weihan Lin was having an affair with another woman, Mei Lin had found out some time back and wanted a divorce, and Weihan had declined to divorce because it was too expensive. Mei had apparently forged his signature to sign and submit the divorce papers, whereas Weihan just found out about it that day and decided to confront her about it. What was this, really- talk about a prime time family soap opera. Young folks these days were really too fickle; no commitment, no morals, no thinking ahead. What were they doing having a child like this and neglecting her?
