In academic science Erdos and in Hollywood Kevin Bacon, that anyone in the industry is within 6 degrees of separation from Kevin Bacon, because he has worked prolifically with many.
Who would be such a person in K-pop?
ONLY idols active in the last 20 years are for consideration.
Who has collaborated, interacted, done something or other, that they can be connected with anyone in the industry within six degrees.?
My candidate is IU, because
Heroes, Dream High, Salamander Guru, The Producers all had a lot of idols at least as cameos.
And then her remake albums, collaborations connect to a lot of older generation artists.
And now her Palette YouTube show, the guest list reaches to the 4th gen or concert guests to 5th Gen.
Another option is Heechul primarily because of Knowing Bros, which many idols visit, sometime or other.
Who do you think can be the Kevin Bacon of K-pop?
