I adore this manga. I'm sad to say that she passed away. There was suppose to be both a sequel and a side story but they were never wrote. There is another series by her but it appear that none or them are scanlated even though the volumes are complete.
You may feel your favorite manga should be gathered together into distinct categories for your own reference and, now, you can do this with a LIST. After you've created your list or lists, you can proudly recommend them to other manga fans to showcase and share your taste in manga.
