About Goong 1.5:
yeah, i won't blame YEH either for telling the white lie. i think goong 1.5 is scripted too. remember JJH thought initially that they still rehearsed the programme. and when he did hoolahop with YEH, YEH asked him sth and he said that the question was not in the script.

but when PKL mentioned about KJK, isn't YEH still very sweet and smart by cupping the ears of the bear doll and pretending that she couldn't hear PKL?

this reminds me of KJK's cupping ears of YEH in the Dangyunhaji battle with Lee Min Ki in Pattaya. by doing this, perhaps she wanted to tell KJK the same thing - she couldn't let him hear what she said!
Also, we can notice how she was sort of whispering when she said she didn't have any boyfriend yet. very brief tone - trying to get the attention away.

I think in Goong 1.5 perhaps PKL was doing a favor for KJK or for both KJK and YEH. I mean she hinted to Goong fans that they should not forget, YEH had a 'complicated' relationship with KJK. they did not discuss how complicated it is though

Now, going back to the scripted issue in xman. i agree that no matter what people said that the show is scripted, they can't deny KJK and YEH's strong chemistry. i don't think that there are scripts for the whole show. maybe just loose scripts, as the general guidelines, we can spot many spontaneous reactions during the show. how KJK looked so blissful after YEH danced for him in Pattaya and that he said the dance he performed was all worth it and that he would prepare more dances in the future. HAAA!!!
i actually admire KJK for admitting he likes YEH very much. look at him, a shy guy, putting lots of courage to admit this! YEH is very lucky

i'm glad that they are very close in real life. it always puts us into impatient feeling, trying to figure out if they are really dating or not. well, let's just conclude that they have a very special, close relationship. see the recent hard evidence - the special ring. you know what i mean
