an angel gets bored with heaven.
the angels doesn't want to obey God anymore.
the angel doesn't want to protect God's secrets anymore.
the angel turns against God.
the angel puts off her white wings,
and puts on the black wings.
the angel goes down to the world below.
the angel feels the pleasure to be the part of the world below.
the angel commits the greatest sin.

will God forgive her?
will God picks her and brings her back to heaven?
will God gives her her white wings again?
will God tells her God's secrets again?
will God trust her again?
