In the play, the development of Ayin and Kuching's relationship is full of twists and turns. Initially, Kuching didn't have much affection for Ayin, but had a good impression of Huashu. However, as the plot progresses, Kuching gradually realizes that the person he really loves is Ayin. He not only rejected Hua Shu's proposal, but also announced in public that he wanted to take back the demigod weapon and draw a line with the peacock clan. In the end, Ayin and Kuching got married in a fake marriage, and the two wore wedding dresses and groom clothes, kissing openly, and Kuching also understood his heart and developed a true love for Ayin.
Another pair of CPs that are highly favored are Yanshuang and Hongyi. In the play, Yan Shuang and Hongyi are a pair of happy enemies. Hongyi rescued Yan Shuang, who was chased and killed by the Peacock Clan, and Yan Shuang had a good impression of him. On Hundred Bird Island, when the peacock clan wanted to make a move on Yan Shuang, Hongyi stepped forward to speak for Yan Shuang, which also warmed up the relationship between the two. In the trailer, Yan Shuang and Hong Yi also had a fake marriage, Yan Shuang almost fell and was pulled by Hong Yi, so the two kissed. Although each other is very strong, deep down they already know each other's intentions.
Although the emotional line between Hongyi and Yanshuang in the original book is regrettable, the pair in the drama version has more foreshadowing and development. Many viewers think that the ending of this pair should be stable, and Yan Shuang should be with Hongyi.
In general, several pairs of CPs in "Shen Yin" have attracted much attention, whether it is Ayin and Kuching or Yan Shuang and Hongyi, their emotional development has made the audience full of expectations and attention.
