She said, "I was happy when we were promoting 'Gee.'  I think it was a moment left as the highlight of Girls' Generation.  We wore heels for the first time.  I thought that we looked like women.  If I look back at it now, we look like babies.  Back then, we were dignified. Thinking about it now, I'm embarrassed.

"The person who pretended to be an adult back then was me.  I got ahead of myself and told the others that now I was going to try to look good with red lipstick.  At the time, I thought that I was an adult now.  Nowadays, when I look at girl groups, I wonder with what thought I claimed to be an adult."
