The Mad Doctor and Poison Princess: Uncle, You're Too Outrageous!

On her wedding day, she is abandoned by the crown prince and becomes the laughingstock of the entire city. She is threatened: if she does not marry, she will die. But what is she supposed to do after casually picking up a bargain imperial uncle and getting completely eaten alive by him?

She gazes at him, troubled. “This was only an agreement. Why won’t you let me go?”

His icy face slowly blooms into a faint smile, instantly locking away her runaway heart.

Her heart pounds. Unable to hold back, she throws herself into his arms. “Ah! You don’t have to say another word. I’ll marry you!”

But then--

A dangerous presence comes from behind. “I told you, if you don’t marry the crown prince, you’ll die. Little girl, how would you like to die?”
