I've Been Looking For a While Now

[Akihiko Yamamoto Hozagaki]

THIS IS NOT A REQUEST

I used the romaji search on animelyrics.com but I just can't find this song. It was a song with a girl who had a soprano voice and the words that I recognized were something like this:

"Ame ni, no retao hou wa
Yasashii todokai kito"

I'm pretty sure "retao" is not a word, but that's what it sounded like o_o. It was a really slow song and the only other instrument was a piano I think. I just really want to find it though, I haven't heard it in a while.
