Butterfly trapped in a jar

She is a butterfly trapped in a jar.
He wants to contain her beauty
but he doesn't know that
her beauty is rare but will last forever
within his eyes.
He just doesn't know it because
she is a butterfly trapped in a jar
and the lid wont open for its sealed..
If his love would show through his mind
the lid may open up
and her rare beauty be infinite.
He just need to prove to her
his undying love.
