The first one is really a reflection book that was delayed by the title. The subject matter is very novel, a bit like a dream in the underworld, and a little sadistic (ಥ_ಥ). The heroine in the second book has lived a long life and has seen all kinds of life, but she may not know much about love or the responsibilities on her body make her unable to love (but it is good that the author did not fill in the story frame for many scams)
