During 2010, she was on hiatus because she was republishing her old manga, in which she was retaining the original plot and updating the artwork.
Alongside with publishing in Kadokawa Shoten, her work is also published in Emerald which is a collaborative shoujo/BL manga magazine with Nakamura Shungiku (author of the renowned Junjou Romantica and more recently, Hybrid Child) originated from the manga Sekaiichi Hatsukoi.
After Kaoru reciprocated Haruka's feelings I don't think there was much left in the storyline. After reading the whole series, I suspect it may have been better off left as a one-shot.
