My heart does know you, and he says he loves you

You're saying love at first sight does exist? 

Yeah

So, Is it possible to fall in love with someone you don't really know? 

I think you fall in love with the idea of that person 

And then? 

Then you know him, and fall in love completely

You can't say that, you don't know me

Oh,  but my heart does, he says he loves you

You're insane 

You have no idea
