okay... I'm kinda confused.. why does she use a French (cover) song to promote her upcoming Japanese (best) album?
Edit: I'm even more confused... The link you posted above.. I look at the paragraph (didn't know much Japanese), but there're some characters (Chinese) implying that she wrote Japanese lyric for that song.
Someone please translate...

..
Edit 2: It seems like she "translated" the French lyric into Japanese lyric. In the cm she sang the French one tho..
