Jungkook’s fav song atm is probably “Palette - IU (feat. G-Dragon)”, I mean his two fav people in the world collaborating???
I think the simple answer/thought about LJK and the dating thing is that its business. He's an entertainer and there's a certain level of "image" he has to put up. Sad truth is that people want to see their idol as a "taken" man cause it ruins the fantasy (this same rule oddly applies to waitressing too.waitresses reported to get more tips while not wearing their wedding rings than when they do). Plus keep in mind that these programs and shows he does bring in a lot of money guys gotta work :)
