Dou *e kimi wo suki ni natte shimattan darou?
Donna ni toki ga nagaretemo kimi wa zutto
Koko ni iru to, omotteta no ni
Demo kimi ga eranda no wa chigau michi

Dou *e kimi ni nani mo tsutaerarenakattan darou?
Mainichi maiban tsunotteku omoi
Afuredasu kotoba, wakatteta no ni (mou todokanai)

Hajimete deatta, sono hi kara
Kimi wo *teita ki ga *an da
Amari ni shizen ni tokekonde shimatta futari

Doko e iku no ni mo issho de
Kimi ga iru koto ga touzen de
Bokura wa futari de otona ni natte kita
Demo kimi ga eranda no wa chigau michi

Dou *e kimi wo suki ni natte shimattan darou?
Donna ni toki ga nagaretemo kimi wa zutto
Koko ni iru to, omotteta no ni (mou kanawanai)

Tokubetsu na imi wo motsu kyou wo
Shiawase kao de tatsu kyou wo
Kirei na sugata de kami sama ni chikatteru, kimi wo

Boku ja nai hito no tonari de
Shukufuku sareteru sugata wo
Boku wa dou yatte miokureba ii no darou?

Mou dou *e kimi wo suki ni natte shimattan darou?
Ano koro mo, bokura no koto, mou moderenai (kangaeta) mou modorenai (kangaeta)

Dou *e kimi no te wo tsukami ubaenakattan darou?
Donna ni toki ga nagaretemo kimi wa zutto
Boku no yoko ni, iru hazu datta (sono mama nii)

Sore demo kimi ga boku no soba nara to itte mo
Eien ni kimi ga shiawase de iru koto
Tada negatteru
Tatoe sore ga donna ni sabishikutemo (setsunakutemo)
