Aishiteru 100nengo mo kimi dake wo aishiteru yakusoku suru yo zutto

“tomodachi no tomodachi” to kimi wo shoukai sarete
Bokura wa deatta ne ano hi
Nanto naku gikochinaku “hajimete” to itta
Dokidoki ga kimi ni kikoenai you ni

Shame okuru kara, to koukan shita adoresu kara
Boku no omoi ga kimi made todoku to ii na

Aishiteru 100nengo mo kimi dake wo aishiteru yakusoku suru yo zutto
Agerareru mono mo nai shi kiyou demo nai keredo
Itsudemo kimi no soba ni boku wa iru kara

Omou koto surechigai kimi ga nakisou ni natte
Jibun ga chiisaku mieta

“gomen ne” to ittara chotto okoru furishite mo
Sugu ni waratte sore de mata suki ni natte

Itsu no hi ka donna koto ga
Bokutachi ni okitatte kanarazu norikoeyou
Shiawase wa yume wo egaki kanashimi wa wakeatte
Ashita wo sagashite ikou sora wo miagete

Bokura ga meguriaeta koto taisetsu ni shitai yo
Tsutsumikomu you ni kimi wo mamoritsuzukeru yo

Aishiteru 100nengo mo kimi dake wo aishiteru yakusoku suru yo zutto

Agerareru mono mo nai shi kiyou demo nai keredo
Itsudemo kimi no soba ni boku wa iru kara
Dokomademo ashita wo sagashite ikou sora wo miagete
