[Verse 1: Sehyung]
The person I love broke up
With the person he loves today
Actually, I waited for today for a long time
I waited for it for a long time

[Chorus: Gowoon, Seoyul]
First love, you're my first love
But when I see him being sad
My heart aches so much
Can't it happen to me like it did for him?
My first love is a love
That I'm doing alone

[Verse 2: Taeha]
The person I love went to
See the person who broke up with him
He told her it won't ever happen again
He begged and begged and now they're dating again

[Chorus: Daye, Gowoon]
First love, you're my first love
I see him brightly smiling
And my heart aches so much
First love, I'm not your first love
Can it happen to me
Like it did for him?
[Verse 3: Sehyung, Seoyul, Taeha]
If I wait, will he come back to me?
If I hurt, will he know my heart?
Every day, every night I pray
When will you know my heart?
Oooh lalalala ooh

[Chorus: All, Gowoon]
First love, you're my first love
(My first love)
I see him brightly smiling and
My heart aches so much
(Hurts so much)
First love, I'm not your first love
(My first love)
If only you can smile like you're doing now
(A first love that will never come true)
