Words alone can't express
It's not something so simple
Even though I'm clumsy
On this special day
I just want to feel closer to you than anyone
Your smile, your voice
Everything about you
Is irreplaceable
My one and only treasure
Just by you being there
Smiling like always
My heart is filled with warmth
No matter how much time passes
I swear to love you forever
That's my promise of love to you
There were days I made you mad
And days we laughed at the silly things I did
No matter what, it's always you
I can't quite put it into words, but
I just want to stay with you forever like this
Even as we grow old, the two of us
Will keep holding hands and smiling together
This endless happiness
Forever and ever
Ah,Even if one day
I'm no longer in this world
I'll be watching over you from the sky above
Even if we're far apart
I swear I'll always be by your side
That's my promise to you
If I had just one wish
Even in another life
I'd want to meet you once again
And fall in love with you all over again
Just by you being here
Alive and breathing
I feel so happy and warm inside
Even if this world disappears
I swear to love you forever
This is my unchanging promise to you
