Nana reveals to be a forgetful person in a recent radio.

Orange Caramel made their guest appearance on SBS Power FM 'Choi Hwa Jung's Power Time' radio on August 25th. During the radio, Nana was pointed out as the most forgetful member.

She said,"It's a really serious problem, I lose my phones for more than 10 times a day. I can't remember the place I put it". She continued,"The behavior is like old mother. Once I even put my phone in the refrigerator, I tried to search for it all day but couldn't find it, then I thought it might be in the refrigerator and it really was there".

Orange Caramel also revealed it costs 800,000 won to make one piece of their costumes.
