Sorry, I didn't think you added random parts! I phrased the question weirdly.. I was wondering what type of text got translated into bitter smile... but it's interesting to learn they actually write bitter or wry smile. In interviews in the West they only say "laughs" with no intonation behind it.. whether it's bitter or sarcastic or anything. KT interviews have a lot of bitter smiles.. :)

Thanks again, and thanks for responding! :D
