Boku no omoi ga itsuka niji ni naru made

Taiyou ga ichi chokusen ni maue made kitara
Seifuku no uwagi wo nuide shuugou da

Koutei ni hoosu hippari dashite
Ikioi yoku mizu wo makichirasou
Kurukuru mawatte shibuki ga tobu
Hizashi no naka

Boku no omoi ga itsuka niji ni naru made
Koushite itai yo
Seisansei nai konna baka bakashii jikan ga
Tsuzukeba ii no ni
Bishobisho ni natte waratte
Kimi to hashiru kono sora no shita
Kira kira to kagayaite iru
Seishun no hibi yo
Konna koi mo ii n ja nai ka?

Ano kumo ga chiheisen wo yukkuri mezashite
Nagarete ittara yagate kaisan da

Houkago no chaimu narihibiku made
Aki mo sezu mizu wo kakeatta ne
Waawaa nigetari oikaketari
Hisashiburi da

Boku no omoi ga itsuka niji ni naru made
Kaeritaku nai yo
Shouraisei nai dame na kurasu no nakamatachi to
Kimi ga ireba ii
Asedarake ni natte sugoshita
Kono isshun no mizumizushisa wo
Itsu no hi ka omoidasu no ka?
Wakai kono kisetsu wo

Guraundo no ue ni
Mizutamari ga dekite
Sora no ugoki wo utsushite iru
Mou sukoshi (mou sukoshi)
Ato sukoshi (ato sukoshi)
Niji wo machitai

Boku no omoi ga itsuka niji ni naru made
Koushite itai yo
Seisansei nai konna baka bakashii jikan ga
Tsuzukeba ii no ni
Bishobisho ni natte waratte
Kimi to hashiru kono sora no shita
Kira kira to kagayaite iru
Seishun no hibi yo
Konna koi mo ii n ja nai ka?
