Lyrics:

Tozasareta doa o akeru no wa
Totte tsukerareta aikotoba
Ichido dake shika iwanai kara
Ai shiteru furi de uketomete
Nani ga kagi da ka wakaranai mama
Dekisokonai no kagi o fuyashita
Yokei na kotoba shaberisugite wa
Dekisokonai no kagi o fuyashita
Daiji ni shisugite anata wa
Daiji na kimochi o kakushita

Tane mo shikake mo bareta tejina
Ichido dake shika yaranai kara
Shinjiteru furi de uketomete
Suteteyuku bakari no watashitachi ga
Yume no shima e to tadoritsuitara
Kitto imagoro tsuki no uragawa
Hitori samishiku hana ga saiteru
Tozasareta doa o akeru no wa
Totte tsukerareta aikotoba
Ichido dake shika iwanai kara
Koe ni dasanaide tashikamete

To open the closed door heres
The keyword attached
Because I'll only say it once
Take it while pretending I love you

I do not know what is the key
I increased the key of the failure
I'm talking too much words
I increased the key of the failure

You are treating too much
I hid an important feeling

To open the closed door heres
Magic tricks with seeds and tricks
Because I'll do it only once
Take it while pretending to believe

We are just throwing away
Once you reach Yume no Jima
Surely now behind the moon
I am lonely and flowers are blooming.

To open the closed door heres
The keyword attached
Because I'll only say it once
Make sure not to say it out loud
