Because I think BLUE seem likes sea,sky... 

  When I feel sad, I always go to the seaside... 

  Look at the blue sea, let my heart feel relax... 

  So..when I grow up, I will let BLUE full my life.. 

  Easy come, easy go.. 

  I have faller in love with you.. 

  It is you who I often miss... 

  Blue fate.. get me lots of smile..
