I think its pretty sad but i dont cry lol. It is quite distrubing that robin rubs herself up against the Tv screen with a picture of Amon on it. Obsessive some might say lol.
It makes me think, and get emotional
Mmm the words are quite thought provoking,
The anime as a whole has some sad moments *sniff*
But overall after listening to the song this morning, when you cant really understand whats being said, cos its in jap and i aint got a good memory for what the eng words are :P. it does sound upbeat.
