It's "Victorian Romance Emma". And it's an amazingly lovely (and historically accurate for the most part) series, where you can tell the writer loves the era so much that she WANTS to get things as right as possible. The artwork is also beautiful.

I don't think the person that wrote the secret was trying to be elitist, only saying that if you are going to get your perception of the Victorian Era from a Japanese comic book, Emma is the way to go. And I have to agree.
