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

I know, you know 

Used to describe a situation where you and someone else are aware of the mistake that a 3rd person is making. For this to be an "I know, you know." the 3rd person should be blissfully unaware of the situation.

"Hasn't Yoshi twigged that bird over there is a shemale?"

"I know, you know."
