The whole story does not have much plot, it mainly focuses on the description of the changes in the relationship between the two protagonists. The story is also a pavement for the relationship between the two protagonists to heat up and make them realize that they actually love each other. It is a short and medium-sized story with a small amount of investigation plot. The whole story is very comfortable to read. It is occasionally bloody, but it is innocuous. I like this sweet and sour taste very much, less sour and more sweet.
