People may miss those years when they could freely use the abilities of angels. Everyone had wings of different colors behind them and developed their own abilities. Although violent conflicts continued, everyone was always happy to face this seemingly blessing from God.
He is the only one who has been unable to transform into an angel since birth. He shuttles among the crowds full of wings and cannot find his own destination. Even if he is bound to a devil's contract in the future, wears black wings, and finally has his own wings, he can only become a lonely devil.
No one can understand the loneliness in his heart, no one can tell the origin of the devil, no one can tell him the direction of the future, no one can wrest a little freedom from his hands.
Facing the end, will he choose to break the deadlock and create ancient miracles, or maintain the status quo and maintain a devastated world full of angels?
