On February 4, HaHa was rushed to the hospital due to extreme exhaustion. According to authorized personal, HaHa was advised to take some time off to recover his strength; therefore, he was not able to host his radio program "HaHa’s Tenten Club." Singers BMK and Han Kyung Il temporarily filled the position for him. HaHa expressed his apologies to his fans for the distress he may have caused them. HaHa is expected to enlist in the army on the 11th for four weeks. After his 4-week required military training, he will finish the rest of his obligatory duties through "special celebrity treatment" community service.
