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."
