I felt the same when I read that interview too.I was wondering maybe I was wrong about them. they are just friends but then I remembered that ep jh had a data with kg, she said kg is the first member jh had a dinner with alone and she just had dinner with ks once but then she add he went to tanning salon with jk several times. maybe she doesn't count jk while speaking about rm members. but I can be just too bias about sa, they can be just good friends .
