Michael Langton is the son of Satan, a handsome man with blond hair exuding the beauty of death and sin.
Chen Xi is an ordinary Chinese international student who picked up a homeless blond boy in front of an abandoned house.
"You can call me sister from now on."
"Sister," the blond boy said shyly.
Crows circled and died over the house every day, and the temperature in the house was ridiculously high.

The wizards also search for Michael, saying that he is their Alpha, a rare genius in the world.

Later, a group of witches captured Chen Xi and placed a curse on her to threaten Michael and prevent him from destroying the world.
What will happen in the future, and what will happen to Chen Xi and Michael.
