It is very rare to see an artist perform on stage barefooted. But for Sunmi, it turns out that it is her secret for a successful solo career and comeback.

On the March 1st broadcast of KBS 2TV's "Entertainment Relay", Sunmi shared, "I think that going barefoot was a God-given advantage because it gave me a chance for me to stand out. I tried to give off the look of being 'not a girl but not yet a woman'. Also, instead of high heels, barefoot suit me more."

When she was asked if she was confident about her figure,Sunmi responded, "Confidence... A little bit?", and give a shy laugh.

It's a good thing that Sunmi stays humble despite of her success as an artist.
