Prologue

"In every angel, a Demon hides
In every demon, an Angel strides~"

Crysella was an angel who, on committing an accidental sin, was sent to Earth as a punishment. Similarly, Evan was a devil, who did a good deed and was also sent to Earth. Both of them were accompanied by two of their friends, and quite coincidentally, they all meet. It was there that they found out many new feelings - friendship, jealousy, fear and maybe love~?
