[Verse 1: Haechan]
Oh, maybe, maybe, this may be love
I already only see you in my eyes
Even if I'm afraid it's not yet
Oh, I think I felt it too

[Verse 2: Mark, Renjun]
The letters in the book became real
I think my heart is about to burst
Oh, I can't, I can't explain it with any words
Yeah, you're the only one for me (Woo)

[Chorus: All, Chenle]
No matter where I am, even in my dreams
Oh, you're the only one for me
I'll risk my life to tell you
There won't be a second chance
You're my last love

[Verse 3: Mark]
Let's talk about love
Let me talk about love
Yeah, I'm talking about you
Yeah, I'm talking about you
Tell me everything
Do I have another chance?
No, you're the only one for me

[Verse 4: Haechan, Chenle, Renjun]
My baby, baby
I'm not clueless due to this being my first time
Everyone will envy us
I'm seizing the opportunity so my first love can last until the end
Even if I don't dance at a club
My heart is dancing with you
I don't know what a drunken feeling is
But I think I'm drunk on you

[Chorus: All, Renjun]
No matter where I am, even in my dreams
Oh, you're the only one for me
I'll risk my life to tell you
There won't be a second chance
You're my last love

[Verse 5: Mark, All]
You, you, it's you, you, girl
It's increasingly getting clearer
I don't want to worry anymore
No more other waiting
It's just you, all I want is you, you, you

[Bridge: Jeno, Jisung]
Even if I look left, right, back and forth
There's no exit from a person like you
You don't have an exit
Even if I could go back to the past and find the way out
I can't find my way back
I'm trapped inside of you

[Chorus: Haechan, All, Chenle]
No matter where I am, even in my dreams
Oh, you're the only one for me
I'll risk my life to tell you
There won't be a second chance
You're my last love

[Outro: All, Haechan, Renjun, Chenle, *Mark*]
(You're my, my last) You're my first and last love
(You're my, my last) You're my first and last love
(You're my, my last) You're my first and last love
(You're my, my last) *You're my first and last love*
