Mune ga dokidoki

Hyaku nen buri no seikimatsu nake to iwarete boku ha waratta
Hisakataburi no seikimatsu hiroi sekai he tobidashiteyuku

Kodomo no koro ni wakari kaketeta koto ga
Otona ni natte wakaranai mama

Eraku mo naishi
Rippa demo nai
Wakatteru no ha mune no dokidoki
Kotae demo nai hontou demo nai
Shinjiteru no ha mune no dokidoki
Mune no dokidoki dake

Kakkoii ka ha wakaranai kedo
Osaekirenai yume wo mitanda
Sakusen tatete jitto matsu yori
Kodomo no mama de butsukatteyuku

Uchuu no hate ni hata wo tateta toshitemo
Uchuu no nazo ha wakaranai mama

Eraku mo naishi
Rippa demo nai
Wakatteru no ha mune no dokidoki
Kotae demo nai hontou demo nai
Shinjiteru no ha mune no dokidoki

Eraku mo naishi
Rippa demo nai
Wakatteru no ha mune no dokidoki
Kotae demo nai hontou demo nai
Shinjiteru no ha mune no dokidoki
Mune no dokidoki dake
