Love poem. What is love？

It's love that makes the world beautiful

What is love?
Love is cruel,love is sweet.

Cruel Sweet,
Lovers sigh till lovers meet,
sigh and meet, sigh and meet,
and sigh again,
Cruel Sweet,
O!Sweetest pain!

>
Love is blind,but love is sly,......
Blind and Sly.
Thoughts are bold,but words are shy,
Bold and shy--
Bold and shy,and bold again--

Sweet is boldness,--
Shyness pain.

Hidden love

I Do not love you!No!I do not love you!
And yet when you are absent I am sad;
And envy even the bright blue sky above you,
Whose quiet stars may see you and be glad.
