English translation:

If this night passes
I'm scared that I might not see you

Those clear eyes
That familiar touch
Your face that I looked at while smiling
Will I not be able to see those again

My every day
You are there
Your every day
I am there
When that moon goes down
And the sun goes up
You who was with me
Will you not be there

If I close my eyes
I think I'll remember the times that we are together
When I close my eyes
I think I will only remember the happy memories

If I close my eyes
If I close my eyes

If I close my eyes
I think I'll remember the times that we are together
When I close my eyes
I think I will only remember the happy memories

If this night passes
I'm scared that I might not see you
If this night passes
I'm scared that I will be left alone
