It is not a serious drama, the style is relaxed, and the whole process is a stream of consciousness black humor.
Background ancient times. The male protagonist is a dandy boy. The story takes the pursuit of the lady in yellow as the main line, unfolding layers of horrifying rumors and legends that have been heard or experienced.
The rumors are illogical, the characters' actions are illogical, and the main plot is illogical.
The story contains horror and some subtle descriptions, so don't read it if you can't stand it.
Finally, the original form of the lady in yellow is a chicken. Just broiler chicken.
