Seo In Young is a solo artist and MC now, but if you remember, back in the day she was in the girl group Jewelry!

And on the July 10 episode of KBS' 'Yoo Hee Yeol's Sketchbook', she was asked, "What was the hardest thing about being in a girl group?"

Seo In Young said, "I don't think this is the answer what people want, but the hard things are hard. We can't eat, and we can't go to the bathroom. And you have to work, but you know how you fight even with family? You see your members more often than your family, so they become your family. But when you have a hard situation [such as arguments], you still have to go to all your schedules together. Then you start talking less and less, and later on you start thinking about whether what you're doing is correct. I think you just start thinking endlessly about thing. Right now, singers look flashy on TV, but they are people, too. And they all start so young. I started when I was 18, but nowadays they're younger, so they must have even more troubles. When I see them in their waiting rooms, they look exhausted, but on stage they're all smiley and cute. It makes me think a lot of things."
