Lin Ruan inherits his grandfather’s paper-offering shop. To repay his “yin debt,” he’s bound to the Underworld App as soon as he takes over.
To find help, he burns some unsold women’s clothes for the “underworld bodyguards,” only to have them land right on the face of the Underworld King, He Yuan.
Even more absurdly, the clothes come with overpowered abilities. They’re the only things capable of hurting the Underworld King.
He Yuan: Fine. Women’s clothes, huh? Sure.
Oh, this hot-tempered kid is pretty interesting. He’d make a great wife.
And so, the aloof Underworld King instantly becomes his “personal bodyguard.”
A sweet, doting romance begins between the underworld and the mortal world, with one running and the other chasing!
