What does Memorial address mean?

[majrakun]

So I looked throughout the Enquiries forum (at least I think I did). Is it just me, or am I the only who doesn't exactly know the meaning behind the term "Memorial address"? I love the album, I love the song, but I just don't get the meaning those two words. Is it just a term Ayu coined, the way she did with LOVEppears? Or do they actually mean something? 0_o

I know the song has something to do with her being in denial about a person's death, but what does that have anything to do with the title?

Am I asking a silly question?
