Being in the public eye and basically growing up in the spotlight, we are always responsible for our actions.

I'm sometimes surprised by myself: no matter how much time has passed, I wasn't able to accept my inferiority complex. But I did.

In hindsight, my darkest time came when I was an idol trainee. My future was uncertain and I always had to ask myself, 'Will I be able to debut?' It was physically and mentally exhausting sometimes.

My favorite song of ours has to be 'Feel Special.' It was a little different than our bright songs that talk about love and general happy things, but we thought the song had a special message.

I want to complement Chaeyoung for her spirit and perseverance. She is never scared of new or unfamiliar things; instead she accepts the challenge. It is really awesome to see this side of her, and I want to learn how to be more brave like her.

There have been moments when I was physically strained, but I have overcome the hardships by staging performances and receiving support from our members and fans.

I will never forget when we won No. 1 on a TV music show for 'Cheer Up.' It was one of our group goals. We put in a lot of hard work in that song, and felt accomplished and were very moved.

I had a lot of fun during all the performances, but the most memorable one was 'Born This Way.' Lady Gaga is one of our favorite artists, and I remember the Once in America had the best reaction when we performed that song for them.

I am pretty bad at doing my makeup myself, so these days, I am learning from a makeup artist. I treat my face as a sketchbook and am gradually trying things that I learned from the artist.
