Noo maybe not every ,but 90% of them, most definitivly !
But yet every single drama is different from the other, its almost never the same. There are some cheseey ones and they usually are the same, but if ur're into those things, U won't mind them being the same. Or u won't even notice it ! Its like all those Vampire movies. There is always a high school girl between two unnatural creatures ! And this so called high school girl doesn't know a thing about cloths ! Always wearing them basic shirts with no colours at all !
