On the April 4 installment of KBS 2TV's 'Yoo Hee Yeol's Sketchbook,' NS Yoon-G talked about her latest sexy comeback with "Yasisi."

In relation to the title, she said, "People think it has an erotic meaning, but it does not - it means 'You're trivial (nuh-sisi-hae).'"

She continued, "I think I should of course be grateful that I'm becoming a hot topic and an issue because of my appearance. �They say that I'm pretty. �However, there are also times I feel uncertain about it. �As a singer, my position feels a bit in the gray area, so I hope to change how people refer to me through this song.

If people refer to NS Yoon-G through body, exposure, and more, then I want the NS Yoon-G on stage to be referred to as the NS Yoon-G who sings this, this, this."

She also showed off her singing skills and English through a cover of Lady Gaga's "Born This Way," so check the performance out below!
