I read an article five years ago. I really liked the setting of a female master and a male apprentice. As the male protagonist, I said that I really liked the feeling of the male protagonist turning from a bright and honorable gentleman to a sinister and paranoid person. The male protagonist has a good hand in painting and writing.
It's been a long time since I've read a book in one sitting, and it's still my favorite. The male protagonist really looks like a puppy and is very cute. The setting of the 18-year-old male protagonist meeting the 3,000-year-old female protagonist is also very sweet. The emotional entanglement between the male and female protagonists is such that I have to slow down every time I finish reading it.
