I seriously can't consider that hug from ep301 simple action from two good friends(bare in mind that one of them is 40 and the other is 34, they are not teenagers anymore. I can't really imagine if any of my friends at that age did that publicly if they are not a couple( maybe it's just me). I also think that none of the rm members except JK will do that to her ( maybe kwang soo will try and do it but he will definitely get kicked by Jihyo)
