My Tsundere Villain Husband Is Jealous Again

She wakes up as a cannon-fodder villainess in a book, doomed to die before the third chapter. She thinks she can cling to her villainous husband's coattails and stay alive, only to discover that this great demon looks cold and arrogant on the outside but secretly cries into her pillow every night.

Gu Wanzhao, the target of the vicious supporting character's mission, scolds her for being a coward who only cares about staying alive, while secretly destroying love letters from one handsome man after another. But on the night the System announces her favorability has reached 100%, his eyes redden as he pins her against the wall. “If you dare run, I'll destroy everything you love.”

Only when he sees the Soul-Locking Mark faintly visible on her neck does the Demon Lord finally unleash his jealousy across all three realms.

“You dare lay claim to even this one's soul?”

“Then I'll punish you for all eternity.”
