Itsuka futari ga
Otona ni nattara
Nani wo katarou
Nani ni waraou

Natsu ga mata yatte kita mabushii hizashi ga
Natsu ga kuru tabi ni kimi wo omoidasu yo
Kareshi ga inakatta watashi-tachi wa dekaketa
Nando mo umi made itsumo futari datta

(Dou demo ii hanashi bakari de)
Bakasawagi kurikaeshi ki ni shinaide it's okay
(Ano koro no futari wa itsumo)
Kowai mon nashi hontou chou tanoshikatta

*1 ano natsu wa kitto asezu ni zutto
Futari no mune ni nokoru yo
Hanaretemo zutto omou yo sotto
U know how much I think of U
Nee oboeteru? natsu no yoru
Donna keshiki mo
Kimi ga ita kara utsukushikatta

*2 natsukashii koe
Ima mo wasurenai
Doko ni itemo
I don't care I'll be there for U

Ima demo natsukashikute waraeru hanashi wa
Tokidoki omoikaeshite hitori waratteru yo
Keitai ni nokoshita hengao no shashin mo
Ano koro no mama no futari wo utsushiteru yo

("donna otona ni naru n' darou")
Watashi-tachi fuan datta netemo sametemo itsumo sou
(Yume wo hatasu tte yakusoku shita)
Futari ima sorezore ni yuku beki basho e

*1, *2 repeat

Hey How ya doin?

Kitto kimi wa kimi no shitai you ni sureba ii

*1 repeat

Ano natsu wa kitto asezu ni zutto
Futari no mune ni nokoru yo
Hanaretemo zutto omou yo sotto
U know how much I think of U
Nee oboeteru? natsu no yoru
Futari sugoshita natsu no omoide wa wasurenai yo
