I pick Ja b/c I liked her lakorn with Pip plus I'm watching her lakorn currently on air with Por. I also like Som, she is very pretty and I think she will be great nang'ek in the future.
I didn't vote yet, but if I vote now, I'd choose Som, since she's so pretty. However, I don't really know if any of them are N'Ek...more like supporting role people to me. They're all too baby face. Unless they come out with a great inspiring lakorn, I don't think I like any of the roles that they've been given.
