Nadech is pairing up pretty well with other people though, he's got a pretty full work queue going.
I think it only seems like so much Yaya+Nadech because they have such a huge following and still one of the hottest younger generation kookwan pairings.
Other couples in Ch.3 around their age doesn't have as much as huge support and following.
Plus since Nadech and Yaya's last lakorn, Yaya's only have her 1 with James Jirayu and upcoming with Mark who she's acted with before already.
While Nadech had one with Taew, one upcoming with Mew, had older one before Rising Sun with Kim and etc.
To be completely honest, they have the best chemistry. But at least Nadech is able to kind of mesh well with other actresses too.
While for Yaya it seems that she's still trying to find herself with other actors but have yet to spark a good fan following with.
With her, I feel she'd be one to be offered a lot of roles but she seems to be very careful with choosing her roles which is good but it seems like she's also careful with who she'll be working with as well all coming down to whether or not she'll be able to be comfortable with or the elders would she her comfortably with.
