a poem from W.Z. to X.Y.

A-B-C-D-E-F-G
where can I find thee?
It is only the start of the alphabet
how can it end with you and me?

U and I, I and U
little by little we can find some more new
not a bad way to start with,  you see?
but how can I make it end with me and you?

In the kingdom of two, U are Q and I am K
like in cards that's Queen and King, two hearts of sunshine ray
and if you like we can make a little j (let's call it Jack)
but how can we sort out the other letters before he grows to be J ?

I know everyone calls you Grace, because you R
grace, and I want to write you a poem in a bar
how about a love poem written in  HTML?
so that our road to the alphabet's end won't be far

But you said NO, a cold N and a bitter O.
You said, Don't let wine spoil your mind and let your love go
just use a human language and I'll be fine
P.S. When can we get to the end that nobody seems to know?

Yes, yes, you are right, wine is no good, that's true.
But don't you see the letters we've been through?
You just picked out 4, so 21 letters are gone.
The flag of V is flying over the kingdom of two.

Hold my hand, here we come to the end: WXYZ
There you are, W-X-Y-Z
interlocked initials of the king and queen
now the alphabet is complete with you inside me
