It has been about two years since season 1 is finished, if I'm not wrong, and there seems to be no news of season 2? I don't speak Korean so I cannot find much information, but the official website doesn't have any update either that's as far as I was able to check.

I really liked it, though.

think it's a case of author's health, which particularly sucks for me because there's another one in which the author had an accident just after the end of the first season, and she's been in coma (?) or something since then.
