You had a simple life, I guess? You were a choreographer for VOCALOID and many other artists. You work non-stop. You were playing the piano and singing a song you created at the Dance studio. Someone found out and you're now writing songs for famous singers and performing for the world? See what happens in, Walk To Fame?
