LOL, I think it's very clear that Fallen Leaves is dedicated to Yunho and Changmin instead of Eunhyuk
Junsu: "The feast of
the stars, shining bright and
dreaming the same dream under the same sky. I load my body onto this festival for
the song we will sing once more some day, and that day is sure to come.. When the flowers fall, we will start again.. Fallen Leaves isn't a song dedicated to a beloved woman"
Stars = W. When DBSK was still 5, someone said that all 5 members were dreaming the same dream. Their dream is singing, so the song they will sing again means that they will be together again. You could interpretate "when the flowers fall" as "when SM gives in" or "when everything (lawsuit) is over". This is my interpretation of it.
Whether it is about Eunhyuk or HoMin, we'll never know if Junsu doesn't tell us xD
I love Pierrot because the music is

, but I love the lyrics even more

It's like a "in your ugly face SM" song
