Now I know a bit why he's leaving, because my japanese teacher did a better translation for me yesterday. She said that he's happy because since a long time he was thinking about doing many other things, and he wanted to do other musics. So he ws feeling guilty to keep it secret from the others. So now he told it he's more happy...
And I took a look on his last commen, I didn't translated it right now, but he's talking to the fans about all the cute letters he received. And the picture attached is: the whole time the whole time love you. Bou
