Ladies, this might be out of the subject but you can just scroll down if you don't want to read. or better yet, don't mind me. I might spoil your Fangirl dream.
Anyway before i start i want to correct my earlier comment to Gonnabeme it should be to QB. I apologize dearly for my mistake.
Ladies im so happy for your comments, you didn't let me down, proving this community compose of people with intelligence. I love you all !!!!
Now let see, gathering all your thoughts and comments lets take it to the next level:
QB: You're idea of animal mating is what exactly on my mind. The next question is When will our male species (JS) going to make the final move to claim his mate? further more, will the mate (PSH) take the bait? Or JGS already made a move that explained their "cool-off" insident?
Vira: After watching the bts and observing YH and his reaction to PSH, i could say we have the same idea. I think YH is attracted to our dear girl, PSH, but his not persuing it because, like QB said, JS already put his mark on SH and his making it obvious to him. That's why YH always distance himself in every way possible (shown in numerous bts) but SH being herself would always pull YH and tease him or playfully talk to him and the poor guy can't do anything but to be with her. It's hard for YH since his having scene with PSH and he also know that JS is keeping tap on him and being careful not to show his attraction to SH. (Observe the commentary video where Shinwoo, GMN and TK scene. The atmosphere is kinda thick, ( i don't know, maybe its only me) YH is little bit uncomfortable and shy to the point of putting the empty bottle water in his face and smiling shyly ( i think his blushing). SH's smile is mysterious while JS is like i don't really know how to discribe, you can watched it and tell me coz i might be seeing it differently. And LHK oblivious of everything, his the only one ( i think) who doesn't know there's something in the air.
Earthprincess: Thank you so much for that response. I don't mind having a long answer. Now, we're on the same wave length. Based on your answer, we could now differentiate where JGS and LHK differ this is the point of the whole question. This is what i've discover based on your answer. The difference between the two, although they are on the same interpersonal end of the spectrum is that LHK is acting on the "Conscious mind" while JGS is acting more on the "Unconscious mind", like what you said "emotions spur more action than thought, when you feel something you are more likely to act more on it than to think of what to do with the feeling." In this case, LHK knows "something" thats why his reaction to SH is clear right from the start ( but if he doesn't know he will have the same dilemma like YH because i know he like SH too.) Anyway, LHK is another topic so i will not go on further with him. While JGS is acting more on his "unconscious" mind since he "act first before thinking" otherwise why would he do things to SH that would make an impression that he like her in front of all the crew and the staff? But this is where the question lies, when will his conscious mind accept his unconscius mind? Or did he already accepted it? If he had then it would explain that he already made a move and further strengthen the theory of "cool-off" thing? don't you think?

Sorry if i spoiled your fangirl thing, its just that i wanted to say this and hope it will not ruin your day.
Thank you for all those who take time reading this. Waiting for your comments.
God bless!!!
