Why do I have a memory in my mind that Moon Crying was written of Kuu's sadness that she felt because of amniotic fluid scandal? It's one of the most saddest Kuu songs ever released so I really think it might be so. I also think that show girl has a little hint of loneliness and sadness in the lyrics if you really think about it. It sounds very cheerful but every time I read those lyrics I just can't help but think, "wow, she must have felt sad when she wrote this song"~
I also think that TRICK is a very dark album as a whole and it makes me think that it was the album where she tried to let all of those negative feelings out but couldn't. I know that at least with UNIVERSE she finally got over that sadness.
These are just speculations I've came up with after I read Koda Reki translation~
