A year ago, Jiang Na carefully prepared manuscript paper for Tang Xun. In return, Tang Xun gave her an autographed novel.After that, Jiang Na not only kept Tang Xun's pet dog secret, but also often helped walk the dog during breaks, and the two established a deep friendship.Now, Liu Qiang reported to Jiang Guangming that one of Zhang Qing's college friends had asked her for information before the incident, but because the person did not have a fixed residence or job, his whereabouts had not yet been found.Recently, Jiang Guangming has frequently felt tired, but her busy work schedule has left her with no time to take care of it.

When Xiao Zhang was feeding stray cats near the hotel, Jiang Guangming learned that Jiang Na had been keen on feeding small animals and even got into a financial dispute over a stray dog.Jiang Guangming didn't pay attention at first, but after returning to the room, she decided to check it out.When they went with Shi Luo, they found that the dog Jiang Na was walking was very similar to Zhang Qing's lost dog, even the dog leash matched.Jiang Guangming learned more about the situation from Xiao Zhang and saw the items left by Jiang Na, including a novel by Tang Xun.

In Jiang Na's diary, Jiang Guangming found an IOU, which was the money Jiang Na borrowed from Xiao Zhang for feeding stray dogs.Later, Jiang Na paid off the loan after paying her salary.Shi Luo compared Tang Xun's postcard with Jiang Na's handwriting and found that 100% of the characters were the same.They speculated that Jiang Na's dog-walking friend was Tang Xun, but they didn't understand why Tang Xun would bring Qin Jiang's dog to Fang Hai.Tang Xun's wife Yang Hui said that Tang Xun did not bring the dog with him when he returned home, so only Jiang Na knew the whereabouts of the dog and the dog leash.

Gu Jiming's new novel was highly praised by the publishing house's president, Wang, but Gu Jiming discovered that Mr. Wang had not actually read his work.Gu Jiming was dissatisfied and asked to postpone the publication of the novel because of his damaged self-esteem.Xiao Zhang told Jiang Guangming that He Peng, the manager of the group buying website, had inquired about Jiang Na from the hotel.Shi Luo contacted Liu Qiang and found He Peng's contact information and address.The two found He Peng and discovered that he and Gu Jiming had a past intersection, and took a group photo together.

As the investigation deepens, the case becomes more complicated and confusing, and more and more characters are involved.Gu Jiming originally planned to stay in Changle due to illness, but Su Zhenzhen went to attend the wedding alone.He Peng and Gu Jiming met for dinner and talked about the police investigation into Gu Jiming.Gu Jiming was sent home by He Peng after drinking. Su Zhenzhen discovered Gu Jiming's lies when she rushed back, but she was not angry.Xiao Zhang found Jiang Na's belongings while cleaning the storage room, and Jiang Guangming took them back.After careful inspection, Jiang Guangming was shocked to find that the words left on the manuscript paper were surprisingly similar to the beginning of "Black Rain". This sudden discovery made her faint to the ground.
