Lovely But Tough Sweetheart

Fuduo, whose life was accidentally taken by the King of Hell, wakes up as an ugly bride who’s just been dumped by her fiancé. Her new in-laws hate her, her real parents don’t care, and even the cats and dogs have the nerve to bully her. 
Furious, she taps into the magical space granted by the King of Hell to fight back against her lousy father, punish the wicked, and carve out a place for herself.  
What’s that? Her husband doesn’t love her?
The once innocent boy quickly transforms into a cunning "wolf", dark and sly, mastering every trick in the book. 
With just one cold glance, he warns, "Touch my wife, and you’ll deal with me."  
Everyone retreats in fear, and the big bad "wolf" turns into a loyal puppy, clinging to her and wagging his tail. “My dear wife, am I behaving well enough for you?”
