Unwanted Love: The forbidden one

Two beings that live together in peace and harmony, Angel's and Demon's being kind to each other with each smile in their faces, BUT that change when human's are born to life. The peace and harmony they made shattered, when human's treated Demon's as enemy, and bad guys. War began to the two being's fighting like there is no tomorrow, many years past but their war never ended, BUT when the God's know about it they separated the two and made Heaven and Hell, to stop the war of the two being's making a realm that seperate them...
