same pairings would be tiring to people if they get paired up once in two years or once in few years, there are many pairings in Thai ET who are paired up many times but people dont feel tired of them. However, to the point a pairing is paired up back to back, it's definitely tiring, on screen aspect. People complain Yadech is over-paired, that I agree, same goes to Mark and Kim, they are the 2nd who got paired like 3 times in rows, 3NNT, PCCK and then TRRR, and same goes with any pairing, but the point is, a couple getting over-paired cuz they are hot atm to the public and viewers, and they show potential to the channel.
We are here tired of the same pairings but the folks in Thai are not. They even ask/petition for their couples to be constantly paired up. In another hand, talking about events, CF's, photoshoot, it's up to how strong a couple's popularity is to the public. Yadech wouldn't be going with each other everywhere, if no one asked them to do. It's all about demand and supply as someone has claimed. Are u tired of seeing Iphones everywhere? Or any apple products? But hey people love apple products. Do u know if one wants to book Nadech or Yaya or both of them, they have to book them 3 months ahead? and not like they can book them either
No one is better than anyone, Mark-Kim is as fresh as bread out of an oven, that's how they are "better" than yadech. Yadech has been famous for couple of years already, of course they aren't fresh anymore, however, they still remain as THE couple to the public, becuz people adore them individually, and together. In the long terms, we will see who is better than whom
