you can watch interview with subtitles @thai.interfanclub igi know what you mean... i secretly wish they are a couple in real life but we know that's not going to be possible at all (sigh)... the chinese have a saying "couple look" and i must say M&M have it - just like how the novel described that people mistake them for siblings.
I saw a couple of their interviews. though i can't understand thai, they are SO natural that i think they even feel just a tiny awkward about it sometimes.
