I heard the dream of smut is the side story of the novel. I haven't read the side story yet because I was saving it to read it later. I was reading the mtl version at the time(it was a lot of time ago), that's why I only read until main story only.
I was planning to read the side story when it get proper translation. But then I got spoiled like this T_T I was really upset, I dropped this for a while.
I felt like it unnecessarily to put that dream in the middle of this story like this. Why not follow the novel properly? I like the novel very much

The dreams of smut honestly came out of nowhere and seemed forced. I know it’s probably fan service, but i was more intrigued abt this story’s plot then for the smut. There was nothing wrong with keeping it a slow burn until the side stories instead of deviating from the novel
