On August 17th, BoA guested on KBS's 'Yoo Hee Yeol's Sketchbook' in promotion of her comeback album, 'Only One'.

The Hallyu star opened up the stage with a live performance of her title track. She also conducted a short interview reflecting back on her 13 year career and a look into what she has in store for her future.

Despite being a veteran to the stage, BoA began by expressing, "I always feel nervous when I'm standing on the 'Sketchbook' stage."

When asked how she felt on reaching her 13 year milestone, she humbly stated, "I always to be considered an idol. I never imagined that I'd be promoting as a singer for this long, though."

MC Yoo Hee Yeol then suggested that she choose key words to describe every decade of her life, and BoA chose 'advance forward' for her teens, 'drive straight' for her 20's, 'temporary stop' for her 30's, and 'parking' for her 40's.

When asked why she hasn't been promoting in Japan lately, she replied with a laugh, "I was too busy being a judge."
