Lyrics: Hidezou
Music: Mai

anata no nukumori     osanai koro no omoide
yomigaeru     sore wa natsukashii kara chi ga naiteiru

yagate owari no toki o     anata wa mukaeru no desu ne

saigo made anata no me o miyou
wasure wa shinai keredo
afuredasu     kobore ochiru

ame no hi mo     kaze no hi mo     aruki tsudzukemashita sagashi tsudzukemashita
wasurenai kara     wasurenai kara     wasurenakereba...
kitto mata aeru     sore wa
yume no mata yume

haruka tooku kanata e...

Notes:
The title of the song is very confusing to many, because the kanji used for the first part of it is one that's not used alone normally, and left up to much interpretation over how to pronounce it. BUT, the ~kokoro~ after it tells you that it is NOT pronounced "omou" or "sou", it is pronounced "kokoro". The ~ after the kanji is just another form of furigana. Although it is just pronounced "kokoro", it gives a double meaning, something like "thought, memory, heart, mind".

The lyrics are printed "aruki tsudzukemashita, sagashi tsudzukemashita"... but in the song it is turned into two verses, each using one of the phrases.
