Glass Mask

A friend in my drama class often explains something by giving examples from "Garasu no Kamen (Glass Mask)", a long running shojo manga, but I don't understand it clearly because I had read only one volume of it, and it was long time a go.

I heard that I couldn't stop reading till the last volume if I would start opening this Glass Mask, so I stopped buying it (that was the time when I had to focus on studying for tests).

Now I really want to read it!, but I have no time to do it.
