Who can help me translate this poem?

Translated by myself, fluent, but not rhyming enough, hehe, the level is limited. Sunshine is lovely, bright, warm, friendly and peaceful. I sing happily with you as if you were the only girl in the world.

I am the only man.

Nothing in today's world can stop it.

We can love each other as before.

This is the Garden of Eden for two people

Nothing can affect our happiness.

I want to tell you something beautiful.

If you are the only girl in the world, this wonderful thing will happen to you.

I am the only boy.

On the first morning in autumn, my father's face was reflected in the mirror I was looking at.
