I honestly can't remember after all this time. Although I only just joined the forum, I've read and appreciated a bunch of their works in the past. Of course the latest of which is Akatsuki no Yona.
I probably first heard about it from a friend of mine, though, who has always been big on Shoujo manga. She tends to link me everything under the sun, so I'm going to assume that it was probably through her, somehow!
