I personally think that there are relatively few people reading it, or maybe it's because it was popular in my ancestors. Now there aren't particularly many people reading it, but there are more ancient texts.
The main subject is suitable for hospitalization (bushi). It is a very interesting rule-based ghost story with unlimited flow and a general emotional line.
The main theme is Shou, rebirth, a campus novel. Shou is a more rational academic master, Gong is a little sun gong, and has a bit of a crybaby attribute. This book is really uncomfortable to read, but it is really good-looking, endless aftertaste, a bit sadistic, but it makes people think a lot. Maybe you will miss some scenery while growing up. Are things that make you feel childish and meaningless? Everyone's growth is a process of loss and gain. I hope that everyone will at least make themselves less regretful when making decisions. When the results are not satisfactory, it is good to gain something in the process!
