dare ni demo
button hitotsu kakechigaete
surechigau hi ga aru ne

shinjiteta no ni
sunao ni narenai mama
hanarete iku senaka ni
koe wo nakushitari

ima sugu ni tsutaetai
kokoro no doa (door) no kagi wa
sono mune no naka ni aru no
makenaide, nigenaide
ikusen no omoidetachi ga
musubi tsukete kureru
just the key of heart

i believe in love, two hearts
i believe ln love, two hearts

gomen ne to
ietara kitto wakaru no ni
kimi ga inakya dekinai

kitto imagoro
onaji omoi daiteru
kizuna ga yonde iru yo
dakara ai ni yuku

ima sugu ni tsutaetai
kokoro no doa (door) no kagi wa
kono mune no naka ni mo aru
me wo tojiru tada inoru
tobira goshi ni hibiku kodou
kimi ni todoku you ni
just the key of heart

meguri ai, kono kiseki
umareta toki mo basho mo
betsubetsu no kimi no mune ni
mayowazu ni tobikonda
futari dake no monogatari
owarasenai yuuki
just the key of heart
