I'm a librarian who loves anime, manga, and reading a wide variety of genres.
Both Noriko and I are unimpressed and a little confused by what's going on right now. The family has told Noriko their secret, supposedly, but since it's part of what she's been accusing them of for a good chunk of the book, it's a little weird that they're suddenly admitting to it now. And everyone in the family is acting like Noriko is some sort of blessed miracle-worker for "healing" a member of the family, never mind that it wasn't that long ago that she told them she knew that person was doing better than they were letting on.
