Tsumaranai nichijou ni anata wa waratte niji o egaita
Konna chigau bokura deau hazu mo nai hazu mo nakatta sa
Nakanaide ite himitsu no yakusoku kienai kizuato
Mamoritai to itte shimaetara kitto raku ni naru keredo
Doushiyou mo nai hodo ni mou hikisagarenai
Hontou no kotoba kikitaku mo nai

Kuchizuke diamond o anata no yubi ni watasou
Katachi no nai yakusoku itsu datte omoidashite
Aishiteru atarashii nichijou to anata ga egaita niji wa mazarazu
Ame ga yanda sora soredemo hikari o matte iru boku wa
Doushiyou mo nai hodo ni mou hikisakarete
Hontou no koto wa shiritaku mo nai

Kuchizuke diamond o anata no yubi ni watasou
Katachi no nai yakusoku itsu datte omoidashite
Shashin ni nokoranai omoide o yakitsukete
Futari no yakusoku ga kuchiguse de owaranu you ni
Oboetete
Boku dake ni miseru hyoujou o mou mitsuketanda yo
Kasaneawaseta kioku kuzusenai yo

Doushiyou mo nai hodo ni mou kakusenai kara
Hontou no koto nado ah koreijou kikitaku mo nai yo
Kuchizuke diamond o anata no yubi ni watasou
Katachi no nai yakusoku itsu datte omoidashite
Shashin ni nokoranai omoide o yakitsukete
Futari no yakusoku ga kuchiguse de owaranu you ni
Oboetete
Ugokidasu nichijou ni anata wa namida de niji o egaita
Futari wa daijoubu korekara no koto wa nani mo iwanai.
