Manhwa

I have started reading a manhwa, called Please! Mr. Bear! (gom- ssi). It is the first Manhwa I have read, and as I thought I like it as much as I do manga. It has made me curiouse though, other than being Korean, is a manhwa any different from a Manga? If so, how, as i have not noticed any other differences.

I think there's a small difference in the style of drawing, as I can always tell manga from manhwa just by looking at the art. It kinda depends on the artist though.
