[Intro]
Kangaetatte wakaranaishi
Aozora no shita kimi o matta
Kaze ga fuita shougo
Hirusagari o nukedasu souzou
Nee, kore kara dou naru ndarou ne
Susume kata osowaranai nda yo
Kimi no me o mita
Nanimo iezu boku wa aruita

[Verse 1]
Kangaetatte wakaranaishi
Seishun nante tsumaranaishi
Yameta hazu no piano, tsukue o hiku kuse ga nukenai
Nee, shourai nani shiteru darou ne
Ongaku wa shite naito ii ne
Komaranaide yo

[Pre-Chorus]
Kokoro no naka ni hitotsu sen o hiite mo
Doushite mo kienakatta ima sara nanda kara
Naa, mou omoidasu na

[Chorus]
Machigatterun da yo
Wakatte nai yo
Antara ningen mo
Hontou mo ai mo sekai mo
Kurushisa mo jinsei mo

Tadashii ka dou ka shiritai no datte bouei honnou da
Kangaeta nda, anta no sei da

[Verse 2]
Kangaetatte wakaranaiga
Hontou ni toshi oitakunainda

Omou dake de mune ga karappo ni narun da
Shourai nanishiteru darou tte
Otona ni na ttara wakatta yo
Nanmo shitenai sa

[Pre-Chorus]
Shiawase na kao
Shita hito ga nikui no wa
Dou warikittara iin da
Mitasarenai atama no oku no
Bakemono mitai na rettoukan

[Chorus]
Machigattenai yo na
Nanda ka nda antara ningen da
Ai mo sukui mo yasashisa mo
Konkyo ga nai nante

Rabusongu nanka ga itai
No datte boei honnou da
Dou demo ii ka
Anta no sei da

[Bridge]
Kangaetatte wakaranaishi
Ikiteru dake demo kurushiishi
Ongaku to ka mou karanaishi
Kashito ka tekitou demo ii yo
Dou demo iin da
Machigattenai darou
Machigattenai yo na

[Chorus]
Machigatte run da yo
Wakatteru nda antara ningen mo
Hontou mo ai mo sukui mo
Yasashisa mo jinsei mo

Tadashii kotae ga ienai
No datte boei honnou da
Dou demo ii ya
Anta no seida

[Verse 3]
(Aaah) Boku datte shinnen ga atta
Ima ja gomi mitai na omoi da
Nando demo kimi o kaita
Ureru koto koso ga dou demo yokatta nda
Hontou da hontou na nda
Mukashi wa sou datta

[Outro]
Dakara boku wa

Ongaku o yameta
