At the press conference on June 10, she said, "'One Fine Day' was a chance for me to let my guard down a bit.  I've always been very clingy with makeup.  However, Hainan is a hot place, so makeup would easily come off.

"There were a lot of staff members and I couldn't delay them, so I wasn't even able to do touch ups.  I had no choice but to put down the makeup.  I wondered if that would actually end up coming off more cute on broadcast.  I haven't been able to see the edited footage yet, but I'm so curious about how my bare face came out."

Probs gorgeous, ChoA, no worries.  You can see for yourself on June 13 when the show airs via MBC Music!
