A demon and an angel fell in love even though their races were meant to be enemies.

The demon was a rebel, always going against the norm and breaking the rules. He was not meant to be in the human realm, and he did not want to be there, but one day he saw an angel and was instantly captivated by her beauty.

The angel, on the other hand, was a loyal servant of heaven, meant to protect humans from demons. When she saw the demon, she was intrigued by his rebellious, bad boy nature.
