kaze fukeba yume no manimani
yuku ate no nai boku wa utau
yume hanabi sora no kanata e

zutto zutto yume wo mite ita
yatto yatto kimi wo mitsuketa

futari aruita komichi naze ka ookiku kanjirunda
kimi no shashin wo daite hitori-kiri nemuru

kaze fukeba yume no manimani
yuku ate no nai boku wa utau
kimi wa ima ukiyo no naka de
waratte kuremasu ka

zutto zutto kimi wo sagashite
yatto yatto kimi wo mitsuketa

natsu no yoru ni wa yukata wo kite hashaida kaerimichi
mata ne to hanasute no kyori ga mugen ni naru

kimi ga suki kimi dake ga suki
tashikame aeta ano hi wa mou
yume hanabi sora no kanata e
kiete iku no desu ka

sayonara wo kuchi ni suru tabi
kimi ni aenai ki ga surunda
kono koe ga jikan wo koete
todoite kureru yo ne

nee nee zutto kimi no koto

kaze fukeba yume no manimani

kimi ga suki kimi dake ga suki
tashikame aeta ano hi wa mou
yume hanabi boku wo nokoshite
kiete iku no desu ka
