In the promo "Let's Start Reasoning", Liu Yuning looks like a villain. In fact, not only he, but also other guests think they are bad people. Although this variety show has a brand-new theme, it attracted some people's attention when it was broadcast. The guests are very strong, including Shen Teng, White, Liu Yuning, Larena, Charlie, Zhou Keyu and Guo Qilin, which everyone likes very much. These people have different personalities. Although the tacit understanding between them is not enough, they can gradually get familiar with each other and become close friends in later reasoning stories.

Liu Yuning really looks like a villain. All the stories take place in the apartment 1 1, and the program group will also build an apartment building for authenticity, so that all guests can feel the wonderful story and the audience can immerse themselves in it. These guests who participated in the recording all stayed in the apartment as new members, but they encountered various suspense on the day of their stay. Everyone seems to have a lot of secrets, and there are emotional entanglements between them. All kinds of stories are interlocking, and finally they need to uncover the ultimate truth together. Liu Xia, played by Liu Yuning, is a pet foster, but when he holds the puppy, his eyes are a little harsh, his clothes are sometimes dark, and his picture is a little gloomy, just like the sick girl described in the novel.

Liu Xia's story line is more complicated. Every member looks like a villain. Liu Xia seems innocent in the story, but she also hides big secrets. White plays the noodle shop owner Bai Sanwan in the story, and there are also emotional entanglements about him in the story. In the black-and-white promo, he holds a heart and smiles slightly, which really makes people feel very strange. And other guests are also abnormal, it seems that everyone is not simple.

Reasoning variety shows contain many elements. In the background of horror music, several guests crowded together. And those suspense colors are also relatively strong. Everyone is a suspect and can't be the murderer. The real murderer can lie, so he can hide in the crowd and it is not easy to catch them. Liu Yuning is tall and suspicious.
