[Verse 1: Eunhyuk, Donghae]
You know
I've been thinking for a very long time
About the word that could explain
Our relationship, in a slightly ticklish way
Passing through this universe
In front of the blue waves crashing
We are holding on to each other
It’s not an illusion, ah
[Pre-Chorus: Eunhyuk, Donghae]
I promise it's true, I still
Get excited and bloom every time I see you
Yeah, we have a theory like
The word "love" grows endlessly
[Chorus: Eunhyuk, Donghae]
Ooh
I can prove it on the moon
The love we’ve engraved on those stars is not just a fantasy
You and I have alrеady proved it countless times
Ooh
Maybе endlessly, boom
Like our universe theory, our feelings for each other
Keep growing, a plausible hypothesis
[Verse 2: Eunhyuk, Donghae]
In your eyes (Your eyes)
I see a gentle truth (Ah)
It wasn’t wrong, yeah, I know it's surreal
Yeah, I know
[Pre-Chorus: Eunhyuk, Donghae]
I promise it's true, I still
Get excited and bloom every time I see you
Yeah, we have a theory like
The word "love" grows endlessly
[Chorus: Eunhyuk, Donghae]
Ooh
I can prove it on the moon
The love we’ve engraved on those stars is not just a fantasy
You and I have already proved it countless times
Ooh
Maybe endlessly, boom
Like our universe theory, our feelings for each other
Keep growing, a plausible hypothesis
[Bridge: Eunhyuk, Donghae]
Don't forget
Even if you momentarily drift away
My heart continues to grow
Just go, oh-oh, oh-oh
[Chorus: Eunhyuk, Donghae]
Ooh
I can prove it on the moon
The love we've engraved on this stage is not just a fantasy
You and I have already sung it countless times
Ooh
Maybe endlessly, boom (Tell me now)
Like our universe theory, our feelings for each other
Keep growing, a plausible hypothesis
