誰にでも
ボタンひとつ掛け違えて
すれ違う日があるね
信じてたのに…
素直になれないまま
離れていく背中に
声をなくしたり
いますぐに伝えたい
心のドアの鍵は
その胸の中にあるの
負けないで、逃げないで
幾千の想い出たちが
結びつけてくれる
Just the key of heart
I believe in love, two hearts
I believe ln love, two hearts
ごめんねと、
言えたらきっとわかるのに
キミがいなきゃできない
きっと今頃
おなじ思い抱いてる
絆が呼んでいるよ
だから 会いにゆく
いますぐに伝えたい
心のドアの鍵は
この胸の中にもある
目を閉じる ただ祈る
扉越しに響く鼓動
キミに届くように
Just the key of heart
めぐり逢い、この奇跡
生まれた時も場所も
別々のキミの胸に
迷わずに飛び込んだ
ふたりだけの物語
終わらせない勇気
Just the key of heart

Dare ni demo
BORAN hitotsu kake chigaete
Sure chigau hi ga aru ne
Shinjiteta no ni…
Sunao ni nare nai mama
Hanarete iku senaka ni
Koe wo nakushitari
Ima sugu ni tsutaetai
Kokoro no DOA no kagi wa
Sono mune no naka ni aru no
Make nai de, nige nai de
Ikusen no omoide-tachi 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 deki nai
Kitto imagoro
Onaji omoi daiteru
Kizuna ga yonde iru yo
Dakara ai ni yuku
Ima sugu ni tsutaetai
Kokoro no DOA 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
Owarase nai yuuki
Just the key of heart

Everyone has days
when they hit one button wrong
And have misunderstandings
I trusted you…
Yet I can’t say how I felt
As I watch your back get further away
I lose my voice
I want to tell you right now
The key to the door of my heart
Is in your heart
Don’t give up, don’t run away
Our thousands of memories
Will connect us
Just the key of heart
I believe in love, two hearts
I believe in love, two hearts
If I could just say sorry
I’m sure you’d understand
I can’t do it without you here
Surely you’ve nursing the same feeling
Right about now
Our bond is calling me
So I’m going to see you
I want to tell you right now
The key to the door of my heart
Is in your heart
I close my eyes and just pray
My heartbeat is echoing around
Let it cross through the door and reach you
Just the key of heart
Though our hearts are apart
Our meeting, and the time and place
That this miracle was born
Has flown to your heart without hesitation
The courage not to end
Our own private story
Just the key of heart
