A fantasy journey is about to begin... 【The comic adapted from this novel is popular all over the world】

Unlike Xin Yun, the students of Class A each had their own dormitory, and as for Yi Luo Xiang and Yan Qingying, the top students, they even lived in luxurious rooms. However... after unanimous requests from Yan Qingying and Yi Luo Xiang, the two of them ended up living in the same room, and even shared the same bed.
The reason for this arrangement stemmed from an idea by Yan Qingying. If Xin Yun were around, then Yan Qingying would have only followed the two from a distance, quietly, and would not have appeared before them.
However, now Xin Yun was not by Yi Luo Xiang's side, and so... as Xin Yun's shadow, she had to protect Yi Luo Xiang in his stead, always being by her side, whether it was eating, sleeping, attending classes, or resting, and even going to the toilet was no exception.
