you know, i know 

Yoonmin moment of the CENTURY!

All this is no coincidence

Just, just, by my feeling

The whole world is different from yesterday

Just, just, with your joy

When you called me

I became your flower

As if we were waiting

We bloom until we ache

Maybe it’s the providence of the universe

It just had to be that

You know, I know

You are me, I am you
