Leeteuk promised to be on stage in Chile.

Yesterday, he was absent from the 'SMTOWN Special Stage in Santiago' because of enteritis. He posted on Instagram and wrote, "Last year, I had a cholecystectomy, and realized after that, it was not as easy to digest. I had stomach pains and diarrhea often. Five days ago, when we were filming, I had continuous diarrhea, but I hoped it would be okay and I got to Chile after 30 hours of travel time. However, my condition worsened, and I want to apologize to our Chilean fans. Because of this, I will definitely be on stage on the 2nd SMTOWN show that will take place today. I'm sorry for worrying you every time with my health conditions. I'll work harder than anyone today. Chile ELF, sorry and thank you."

Hope he's recovered!
