Having only just returned last month with their hit song, "I'll Be Back," the 2PM boys are already saying goodbye on the November 6th episode of Music Core. Having excited fans in every performance with their "Terminator pose" and shuffle dance moves from their new song, it's a pity that we won't be seeing it anymore on a weekly basis. Check it out one more time below as the boys will next prepare for full-fledged Japan promotions! They also made a cameo during Psy's performance.
