君といつまでも (kimi to itsumademo)

In the twilight enveloping us two by this window
Even tomorrow, wonderful happiness will come
Your eyes shining like stars
This chest in love is burning like flames
Even if the big sky is dyed in sunset colors
Our hearts will not change forever
(declaration)
Isn't it happiness?
The happiest thing for me is being with you
I... won't let you go until I die
Isn't that right?
You let your hair flutter in the gentle breeze
Kindly stay by my side
Even when the leaves fall and time passes
Our feelings will never change forever
