Not a huge fan of Yadech but I think they would make the most adorable couple. My gosh, like Ken and Ann, their chemistry onscreen and off is just amazing. Everything about them looks cute. When I see them together, I tend to find myself smiling because they are THAT cute.
I also wish Ploy and Dome were still a couple.
They look good together too.
Also, Bie and Fang looks cute together.
And yes, Aff and Aum, Ken and Ann...hmm...Tik and Cherry (I thought they were a real couple while watching Kaew Tah Pee a few years back).
