HaHa shared that his personality has changed.

On the October 23rd episode of MBC Music's 'HaHa's 19TV Mutiny', the "Ha-vengers" and HaHa expressed that he's been acting different lately. Though the rest of the Ha-vengers dressed as heroes from comic books, HaHa dressed up as the villain Joker from Batman.

Song Joon Keun said to HaHa, "Joker is not a hero. He is a villain." HaHa responded, "My personality has changed. After receiving grace, I've become kinder," posing like he was praying.

Park Keun Shik looked at HaHa's hairstyle and commented, "You dyed it too much.  It makes you look like Song Dae Kwan." Mino added, "It's not Batman, it's Tae Jin Ah. Then Tae Jin Ah's son is Eru. [The villain] Penguin is Hyun Chul, and Penguin's henchmen are a cluster of bees (a reference to an old pop group called Hyun Chul and the Bees)," which brought laughter on set.
