Letra da Música Yakusoku de Aiko

itsuka mata aeru hi ga kuru deshou
so no hi made kanarazu genki de ite ne

natsu no kumo ga tsukuru GURANDO ni hiita hakusen no you na sekkai mau shunkan
anata no naname ushiro ni ita toki itsumo omoi egaita tsuyoku awai ashita

ima mo yume ni miru yo anata no kienai kage

itsuka mata aeru hi ga kuru deshou
so no hi made kanarazu genki de ite ne

huyu no kumo wa tsukuru hosoku setsunai kiito de anda usui SUTO-RU no nami

kyou wa sayounara kyou de sayounara

namida no tsumetasa te no nukumori anata no netsu memai
hureta a no hi

koe wa chiru sora ni atashi o nokoshite
sakurairo no hanabi
shuiro no KO-TO

donna koto ga atte mo wasuretari shinai
shiawase mo itami mo towa no yakusoku
itsuka mata aeru hi ga kuru deshou
so no hi made kanarazu genki de ite ne
genki de ite ne
