Donna kotoba demo oboete iru
Kono mune ni zenbu shimatte oku no
Chiisa na omoide sae mo kobosazu ni
Kagi wo kakete kyou kara takaramono

Soba ni irareru jiyuu
Kuchi ni daseba kowaresou de kowakute

Zutto himitsu no mama de dare mo shiranai keredo
Konna ni anata wo ai sete sore ga shiawase

Ienai kimochi wa kyou mo yureru kokoro ni
Tayori nage na Nagai kage wo otoshite iru
Hanarete omou dake no Ima wa hitori
Dakishimeru Sabishii kedo suteki na kyori

Furimuku kata ni seotta towa no sora e
Tabidatsu tabi setsunai yo
Anata ga kizukanakute mo dakishimete kurenakute mo
Hohoemu Anata wo ima mitsumete itai

Zutto himitsu no mama de dare mo shiranai keredo
Konna ni anata wo ai sete Sore ga shiawase
Hiza wo kakaete hitori nakitai yoru mo aru kedo
Mata ashita au toki ni wa kitto egao de...

I remember each and every word
They are all shut in my heart
Without letting even the tiniest of memories slip out
I lock them up with a key and from now on, they are my treasures

If this secret comes out of my lips
I fear I'd lose the freedom to stay by your side

As long as it remains a secret, noone would know
Loving you in this way, that is my happiness

I entrust these inexpressible feelings to my shaking heart
A long shadow falls
From afar I think of you, I am alone now
I shall embrace you in my mind, it's sad, but it's a wonderful distance

The journey to the endless sky is painful
Yet I bear it as you turn away
Even if you do not notice me nor embrace me
I will smile, now I just want to keep looking at you

As long as it remains a secret, noone would know
Loving you in this way, that is my happiness
There are nights when alone, I clutch my knees, wanting to weep
When we meet again tomorrow I'll surely meet you with a smile...
