at first i also think like you, but suddenly i realize that maybe it was their strategy to promote their movie since they played as lovers, just wait till the movie end there will be no interaction at all like what happen to mark, nadech once said no matter how busy they are, in the end they will always find each other, thats mean they could be working with other but in real life they will always be together
see how proud yaya to say that nadech was really handsome and have the best body, yaya also said no body could take nadech place
