All I know
Actually, you know
Your heart
After a particularly tough day
I know
What kind of heart it is
You who are trying hard to smile (you who are smiling)

Next to you who are exhausted
I will become your light
I promise to you
I promise

Because I know
When I look into your eyes
A universe filled with me
Am I dreaming?
Baby, you, leaning on my chest
Embracing your shoulders
I will always be by your side
With you

By your tired side
I will become your light
I promise to you
Remember

Because I know
When I look into your eyes
A universe filled with me
Am I dreaming?
Baby, you, leaning on my chest
Embracing your shoulders
I will always be by your side
I know

I know
I am gradually being colored by the color of you
The way we resemble each other one by one is the same as you
You know
If you feel the same as me now

Because I know
When I look into your eyes (your eyes)
A universe filled with me (universe)
Am I dreaming? (Is it a dream?)
Baby, you, leaning on my chest
Embracing your shoulders
You who will always be by my side
I know
I know

La-la, La-la-la-la-la
La-la-la-la, la-la-la-la-la

Because I know
