On the December 9 broadcast of SBS Power FM's 'Kim Chang Ryul's Old School', DJ Kim Chang Ryul wasn't afraid to ask Nicole what had been on many people's minds. He asked, "You were normally a part of KARA, and now you're meeting fans as a solo artists. Isn't it tiring by yourself?"

Nicole responded, "Promoting solo, I do get stressed out. Since I'm by myself, I have a lot of thoughts and worries, so I don't gain weight. Usually, I'm the one who has problems keeping weight off, but these days, I lose weight no matter how much I eat." The DJ replied, "I guess it was the weight loss that made you prettier."
