歌詞: Koda Kumi. Believe.

Modosenai kako modorenai kako
Mata yowai jibun ni kidzuita
Kimi kara sayonara "sore de owari na no?"
Ienai kotoba ga namida ni kawatteku

Kizutsukanai koi nante hontou no koi ja nai
Kimi to no kizu nara kowakunai

I Believe tsuyogari na boku wo
Mou ichido mite kureru to sou shinjitai
Listen to my heart sunao na kodou wo
Furueru karada kono ude de dakishimeta mama

Koushite mainichi tsudzuite yuku mono to
Omotte ita n' da kore kara mo zutto
Kimi no mitsumeru sono saki ni wa mou
Boku wa mou utsutte inai no?

Nanika wo taisetsu ni shiyou to suru to mata
Taisetsu na mono wo kizutsukete ita n' da


I Believe kore kara mo zutto
Kimi wo warawaseru no ga boku datta noni
Listen to my heart sunao na kimochi wo
Hitsuyou to shite hoshii itsu demo soba ni iru kara

I Believe tsuyogari na boku wo
Mou ichido mite kureru to sou shinjitai
Listen to my heart sunao na kodou wo
Furueru karada kono ude de dakishimeta mama

I Believe kore kara mo zutto
Kimi wo warawaseru no ga boku datta noni
Listen to my heart sunao na kimochi wo
Hitsuyou to shite hoshii itsu demo soba ni iru kara
