Hyakunen buri no seikimatsu
Nake to iwarete boku wa waratta

Hisakata buri no seikimatsu
Hiroi sekai e tobi dashite yuku
Kodomo no koro ni wakari kaketeta koto ga
Otona ni natte wakaranai mama

Eraku mo nai shi rippa demo nai
Wakatteru no wa mune no dokidoki
Kotae demo nai hontou demo nai
Shinjiteru no wa mune no dokidoki
Mune no dokidoki dake

*** Break Musical ***

Kakkoii ka wa wakaranai kedo
Osae kirenai yume wo mitanda

Sakusen tatete jitto matsu yori
Kodomo no mama de butsukatte yuku

Uchuu no hate ni hata wo tateta to shite mo
Uchuu no nazo wa wakaranai mama

Eraku mo nai shi rippa demo nai
Wakatteru no wa mune no dokidoki
Kotae demo nai hontou demo nai
Shinjiteru no wa mune no dokidoki
Mune no dokidoki dake

Eraku mo nai shi rippa demo nai
Wakatteru no wa mune no dokidoki
Kotae demo nai hontou demo nai
Shinjiteru no wa mune no dokidoki
Mune no dokidoki dake
