Based on a true history

Her: You know what?
Him: What?
Her: I love you
Him: I know it, and it makes me happy
Her: And you, do you love me?

Him:I'll just say one thing
I'm not going to tell you directly because I say it so much.

I wake up earlier to see you because I love you

I leave my house to wait for you in the subway

And when I'm think, I'm going to die, I only think in one thing, 

And that thing is you.
