While cultivating on Konglin Mountain, Jian Che, son of the Heavenly Emperor, met You Ning, the Demon World's Saintess. She kissed him.
Konglin Mountain was destroyed, his master died, and Jian Che lost his memory. You Ning took him to the Demon World, where they secretly fell in love.
By chance, he returned to the Heavenly Realm, only to be forced into a political marriage with Yan Rou, the Demon Realm Princess. How could You Ning put up with that?!
As a notorious witch across all four realms, of course she'd go and steal the groom!
But later, a blood feud came between them...
P.S. Arrogant male lead × crazy female lead
Both powerful, both devoted to each other, happy ending
(The male lead's body is eventually remade. He doesn't truly die. Neither lead is a perfect character.)

Message: Some things cannot be forced.
