It's true lakorn terminology has evolved over the years, but I believe some terms remain intrinisically the same. Technically, all "n'ek" really means is the female lead, which would definitely refer to Pancake, but to do so would be transferring Western ideology onto Thai culture. Since this is clearly a Thai lakorn based on Thai values, "n'ek" often refers to the lead good girl who normally ends up with the p'ek at the end - one who is supposed to set a good example for society. In that instance, Grace would be the n'ek and Pancake would be the n'rai. Some people might not think it makes that big of a deal, but if it didn't, why aren't Thai lakorns just called Thai dramas like the rest of the world? (Though, just so you know, on a personal level, I consider Pancake the n'ek, too. It's only in reference to who's the n'ek and who's the n'rai would I make the distinction that Grace is the n'ek and Pancake is the n'rai.) Lakorn terminology needs to evolve just a little more and come up with a term to describe a n'rai who takes center stage in a lakorn, like Pancake is doing.
