Ano hi, kimi to nagashita namida
Ima mo omoidasu yo
Toki nagare kakaeru mono mo otagai iro iro fuete kita kedo
Mugamuchuu de hashitta ano koro
Nanimo nakatta kedo
Nani yori mo nan demo atta
Sukoshi wasure sou ni naru

"Saraba, seishun yo"
Sonna kotoba wa uso darou na
Kitto bokura, ano koro no bokura wo koeteta no ni tsuku
Saikou no Best Friend

Toki ga tatte mo kawaranai
Sasaeaeru tomo to waraeru you ni
Tatoe donna tooku ni hanarete mo
Wakatteru yo kimi rashiku waratteru sa
Kanashimi mo ase mo kuyashisa mo
Zenbu kondo warai nagara hanashi kiku yo
Mune hatte ashita wo ikiru akashi
Kakagete ikou ano hi bokura warau

Mada minu asu wo omou amari
Taisetsu na toki sura
Taikutsu datte tsuyogatte ita
Sore mo machigai ja nakute

"Saraba, seishun yo"
Sonna kotoba wa uso ja nai ka
Kitto bokura ano koro no bokura wo
Koeteta no ni tsuku
Saikou no Best Friend

Atarimae no hibi nanka nai
Sasaeaeru tomo ga oshiete kureta
Tatoe donna tooku ni hanarete mo
Wakatteru yo boku rashiku waratte iru sa

Kanashimi mo ase mo kuyashisa mo
Zenbu kondo warai nagara hanashikiite
Mune hatte ashita wo ikiru akashi
Mayou michi wo terashi dasu hikari de are

Nagasare sou na toki no naka de
Miushinau koto mo aru darou
Mayoi sou na toki no naka de
Wasure yuku koto mo aru darou

Soredemo kawaranai mono ga
Bokura ni wa kitto aru darou
Sore wo koete ikeru mono ga
Bokura nara kitto...

Toki ga tatte mo kawaranai
Sasaeaeru tomo to waraeru you ni
Tatoe donna tooku ni hanarete mo
Wakatteru yo kimi rashiku waratteru sa

Kanashimi mo ase mo kuyashisa mo
Zenbu kondo warai nagara hanashikiku yo
Mune hatte ashita wo ikiru akashi
Kakagete ikou ano hi no bokura warau

Oh you're my BEST FRIEND

Mune hatte ashita wo ikiru akashi
Massugu ni sonna deai wo arigatou
