On the latest episode of KBS 2TV's 'Happy Together', the rappers of Dynamic Duo gave a formal apology to former H.O.T member, Tony An, sparking the curiosity of viewers. Back when Dynamic Duo was just starting their career, they were disdainful against all types of Korean music. They harshly criticized the legendary H.O.T in their songs, saying that H.O.T were the music industry's biggest flaw. The MCs were shocked by this story and asked if they had ever fought with the idol group. The set howled with laughter when Dynamic Duo responded that because they were such nobodies, no one even knew that such a song had been released. To make matters worse, Tony An ranked higher as a soldier than Dynamic Duo in the army, but he acted kindly to them, not knowing what kinds of things the rappers said about him 10 years back. "We were so immature and thoughtless", they said in regret. "You don't suppose we'll be awkward after this programs airs, do you?", they cautiously asked.
