I don't know (japanese version)

Kon'nanimo bebī-sukina nda yo
Nanoni kimi wa imaichina no

Fukurande osae kirenai yo
Hyaku man-kai shita sōzō muda ni shinaide

Mukuwareru to ka kanau koto yori tsutaetai yo gibu your love to me
Mazuwa kyori o chidjimetai

Nando mo kurikaesu shimyurēshon dokidoki suru no wa koko kara yo
Hanarenai de zuttoisshoni ireru yō ni
Todoite tte au tabi ni kokoro de saken deru itsumo I love you
Dakedo kimi wa wakattenai ne
Damena nda yo zenzen kimi nashida to

Onegai I'mēji-dōri ni kanae sasete ne
Amai omoi ga kasanaru shunkan sekaihakawaru kara kitto

Motto kyori o chidjimetakute
Nando mo kurikaesu shimyurēshon

Dokidoki suru no wa koko kara yo
Hanarenai de zuttoisshoni ireru yō ni
Todoite tte au tabi ni kokoro de saken deru itsumo I love you

Dakedo kimi wa wakattenai ne eburidi
Ando night nemurenai kurai
Rabingu you tomaranai uketotte all my love
Sorenanoni you don' t know wow oh 〜
Todoite tte au tabi ni kokoro de saken deru itsumo I love you
Dakedo kimi wa wakattenai ne nanimo
