Hagness is a condition in which idols reach a certain age that makes them no longer interesting to Min Hee Jin.
Lee Ji Eun of the kpop group IU, however, does not concern herself with trivial matters such as mortality and the passing of time. She has made her presence in all recorded points of history, and in different planes of existence (with unconfirmed dating rumors with Morpheus of the Endless).
This is how I can say that the term hag is inapplicable to her. I rest my case.
