On July 5, Hongki shared the photo below along with the message, "Ah. Come at me, boil! Come at me again! What do I do about the show..." Fans know Hongki has been battling a painful, recurring boil on his butt since 2015, and it's reported he's undergone 8 surgeries in total for the issue.

Previously on MBC's 'Omniscient Interfering View', Hongki revealed the pain he experiences due to the boil as well as having to have his manager disinfect the abscess.
