In episode 5 of Hometown Cha-Cha-Cha, it was mentioned that Chief Hong’s life five years after graduation is one of the three mysteries of Gongjin. Characters who are close to Chief Hong speculated as to his whereabouts during those five years. One surmised that he was a spy sent to North Korea, one presumed that he became a member of the National Intelligence and faked his identity; some rumors even go to extreme lengths of theorizing that he went to Africa, swam the Pacific, climb the Everest, even the idea of him being locked up in an asylum and incarcerated for murder.
