While learning the song Nadasousou, I can't help feeling the deep longing of the person who composed those lines in the lyrics:

I whisper "thank you" as I leaf through this old photo album, to the one who always cheered me on, within my heart. And should the memories of that smile I think of, come rain or shine, fade away into the distance, they return in the days I search for a glimpse of your face, a stream of tears.
The memories of that smile I think of, in sorrow or in joy. And if you can see me, from where you are, I'll live on believing that someday we'll meet again...
If only we could meet, if only we could meet, my feelings for you, a stream of tears.
Watashi to shite wa, aitakute, aitakute, kimi e no omoimasu...
(wuff-wuff! whimper~)
