Only I didn't know (나만 몰랐던 이야기)

Honestly, you just left me
Your face that used to look at me so warmly
Now it hurts to see you like this
A life I can't seem to start again
Tears are about to spill over
I can't even say goodbye
I just want to show you like this

A good goodbye, but in the end, it’s just a lie
If I knew then, I would’ve cried it all out
At that moment, what I was feeling was just a lie
A story I didn’t know at all

Love wasn’t supposed to be like this
It felt like time stopped next to me
Now it seems like I only know pain
Why did you have to say sorry?

I think I was too naive
At the moment you left, I was just waiting
How much did I laugh back then?

A good goodbye, but in the end, it’s just a lie
If I knew then, I would’ve cried it all out
At that moment, what I was feeling was just a lie
A story I didn’t know at all.
