Ayashiku kagayaita tsukiyo ni toikakeru
Doko made yami na no ka itsu made ima na no ka
Tooku satta kaze ni kataru
Hito wa wake mo shirazu ni
Kotoba wa subete takaku mau
Sei naru yami hikikomarete
Hoshi sae kao wo aozamete
Hikaru koto wo yamete shimau
Mukashi no tomodachi ni moratta kotoba dake
Chiisaku kagayaite uchuu no chiri ni naru
Haruka kanata kaze wo tsurete
Dare mo wake mo shirazu ni
Mayotta ai no omoide ga
Kanashii hodo sora wo kakeru
Mirai wa kimi no mune wo saki
Hohoemi sae kowasu darou
Tooku satta kaze ni kataru
Hito wa wake mo shirazu ni
Kotoba wa subete takaku mau
Sei naru yami hikikomarete
Hoshi sae kao wo aozamete
Hikaru koto wo yameru darou
Mayotta ai no omoide ga
Kanashii hodo sora wo kakeru
Mirai wa kimi no mune wo saki
Hohoemi sae kowasu darou
in all three lines, the reading "wake" is given to the kanji "riyuu." both mean "reason."
