Doushite... kimi wo suki ni natte shimatta ndarou?
Donna ni toki ga nagarete mo kimi wa zutto
Koko ni iru to omotteta no ni

Demo kimi ga eranda no wa chigau michi

Doushite... kimi ni nani mo tsutaerarenakatta ndarou?
Mainichi maiban tsunotteku omoi
Afuredasu kotoba wakatteta no ni (mou todokanai)

Hajimete deatta sono hi kara kimi wo shitte ita ki ga shita nda
Amari ni shizen ni tokekonde shimatta futari
Doko he yuku 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

Doushite... kimi wo suki ni natte shimatta ndarou?

Eien ni kimi ga shiawase de aru koto tada negatteru
