Queen of K-Pop, BoA, appeared on 'Yoo Hee Yeol's Sketchbook' on May 29 and showed how hard she had worked on her latest album, 'Kiss My Lips.'

She said, "This year is actually a very meaningful year.  I wanted to create music that could be a special gift for not only me but also to my fans.  That's why I thought to myself, 'Should I try writing all [the songs]?' and that's really what ended up happening.  I came home in regret and kept kicking my blanket.  Like that, I wrote about 20 songs starting in June last year.  I was able to really study a lot."
