Just as God created his Archangels, the Devil created his archdemons.  Always at odd ends, a never ending game was played.  Humans became their pawns. The rules are easy, make them fall into temptation and bring their souls to the dark side or save them and bring them to the light. But there's always unaccounted factors that affects the game. And love is one of them.

A love that transcends all boundaries. Lovers who can only meet at night, one becomes the light to the other's night.

Where they first met and their lives changed. The only thing that connects them is the cafe.
