**Currently watched this Japanese Drama yesterday online on crunchyroll after found out the DVD of the JDrama is sold at one of our local Cd Shop ( only for B$17/-). I start read this manga and bought it at singapore in 2004. Unable to buy till the last copy of this manga I start read the manga online in Onemanga this year until the end of the manga. I am glad that they make it into drama, but some of the manga in japan they make it into ANIME. So far there are no ANIME for this tittle probably in the future.
