Lyrics
Moshi ano hi no ame ga Tonde itanara Kitto sure tokutte itadakeka mo Itsumo toori no jikan ni  Bus ga kitetanara Kimi to wa deau koto ga nakattanda ne

Moshimo sukoshi demo Ano shunkan ga zuretetara Futari wa tokutta unmei wo tadotte shimatteta

Kimi to onaji mirai wo Zutto issho ni mite itai Onaji hoshi wo onaji bashou de Mitsumete ita you yo  Kimi no egaku mirai ni  Watashi wa iru no kana Onaji sora wo onaji omoi de Miagete ita yo

Kuchiguse ya shigusa mo Yoku nite kita futari Maru de zutto mukashi kara shitteru mitai da ne Douji ni meeru shitari Onaji koto omottari Akai ito de biki yoserareteru no kamo

Guuzen wa saisho kara Mou kimatteta mitai ni Kasanatta futari wa unmei tte shinjite iru yo

Kimi no egaku mirai ni Watashi wa ino kanaru Onaji sora wo onaji omoi de Miagete ita yo

Kimi to onaji mirai wo Zutto issho ni mite itai Onaji hoshi wo onaji bashou de Mitsumete ita you yo  Kimi no egaku mirai ni  Watashi wa iru no kana Onaji sora wo onaji omoi de Miagete ita yo

Tatoeba namida no hi mo Hare no hi mo futari de  Onaji michi wo itsumade mo  Te wo tsunaide arukemasu you ni

Kimi to onaji mirai wo Zutto issho ni mite itai Onaji hoshi wo onaji bashou de Mitsumete ita you yo  Kimi no egaku mirai ni  Watashi wa iru no kana Onaji sora wo onaji omoi de Miagete ita yo

Moshi ano hi no ame ga

Tonde itanara

Kitto sure tokutte itadakeka mo

Guuzen wa saisho kara

Mou kimatteta mitai ni

Kasanatta futari wa unmei tte shinjite iru yo

Kimi no egaku mirai ni

Watashi wa ino kanaru

Onaji sora wo onaji omoi de

Miagete ita yo

Kimi to onaji mirai wo

Zutto issho ni mite itai

Onaji hoshi wo onaji bashou de

Mitsumete ita you yo

Kimi no egaku mirai ni

Watashi wa iru no kana

Onaji sora wo onaji omoi de

Miagete ita yo
