Yadech - I loved them in DJA but after that, I just couldn't get into them. But I do agree that Yaya has the most chemistry with Nadech, out of all her co-stars. As for Nadech, I think he can do way better. I mean I think his chemistry with Taew is way better than with Yaya. And here is when you realize that Yadech has been paired up too many times, when you can't even think of other actors or actresses that they acted alongside with. I see thy have chemistry, but it's just that they get paired up too much to the point where it's too annoying.
MarKim - I'm not saying I don't love them, but same as Yadech, they get paired up too much, but still not as much as Yadech. I agree that Mark still needs improvement on his acting, but Kim's acting is already amazing, even Ananda says so. He says that she knows how to work with the script and even when he goes off script, she knows how to bring him back. Like Yaya, Mark has the best chemistry with his KooJin which is Kim, but like Nadech, Kim can have amazing chemistry with her other costars. As of Kim looking more mature than Mark, it's not a bother to me, because either way, I know that she is actually younger. Also with Kim having a bigger build, it doesn't bother me too. It's life, you can't expect every couple to have a big tall muscular man with a petite woman. "Love" and life just doesn't work like that, so I learn to accept it.
Weir&Min - I just don't get this couple. Min was so stiff and all that viewers loved were just all the intimate scenes between them.
Weir&Pancake - I see no chemistry.
Weir&Mai - I am a big fan of Mai so I tried to watch their lakorn, but I didn't finish it because there was no chemistry and they were just awkward.
Mark&Mint - I thought they were cute, but I didn't like Mint's acting. For me, Mark's acting was a bit more tolerable than Mint's. There's just something about Mint when she talks that is not attractive.
Great&Matt - I just don't see what's the hype.
Honestly to say, I don't see the hype between any couple because it's just a drama and it really just depends on the script and the actor or actresses ability to get us to believe that they are that character or not. Some just do a better job than others. So I can love any actor/actress by them selves, but it will take their best to get me to get into their onscreen pairing.
