us..

Let's flashback to the time
when we were just a friend
when we were just saying "hey" to each other
when there was only "you" or "me"

The first time you text me
with a little "hey"
then continued with some messages
that only us could know the meaning

The next day
we start to talk
just a first-simple-talk
with some undefined giggles

Now
there is not only "you" or "me"
but replaced with

...us
