True. Ch3 isn’t very open to freelancers. Only the ones who bring in money for them like Cheer and TonoCh3 is too crowded. They're not gonna promote Kwan over their top 9-10 actresses A-list crew. Look at Mai D. She only got one with Ch3 and that was with her fellow pan-lan p'ek Mario cause they thought they could milk that cash cow. But GMM and One 31 open their arms to everyone so maybe she can find her place there.
About Nadech, chemistry is truly in the eyes of the beholder. I thought he had chem with everyone including Mew, Taew, Pat and Kim. In LSR, the story was literally about Nadech's character trying to hold himself and his feelings back from n'ek so as to not reveal the twin swap. Maybe that's why some interpret it as Nadech the actor holding back when his character is suppose to be that way?
