What? It's completed? :0
Yes, the last chapter for the main story was released 2 months ago (in Korean). Since then only 4 side stories got released. Of course it doesn't have to mean that the author will never continue the story (maybe we're lucky and she feels like continuing it in the future ;) ) but for now it ends after 27 chapters and some side stories.
I'm kind of disappointed that it's only 27 chapters plus a few side stories long :( . I really hoped it would be longer.
