i suggest to read this book, and read some fluffy good ending after to clean the aftertaste, but these stories have their merits,
i use this reader from only 3/4 years, but i remember maiden's cake like one of the manga that "iniziated" me to the yuri,
i don't think is a "age" matter, the prticular feeling that i have from this autor, i did't find it anywhere, it's very unique, and i have some problem to image a romantic involvement with a satisfaing ending at the age of the characters of these stories.
i think the melancholy of this book is like the angst for a teen story, i can't explain better... but i think is wort of the time
