I'm an ordinary designated driver. One night, I get a ride request from the underworld, and my customer turns out to be a red-clad female ghost floating in midair! She forces me to help her escape a ghost marriage and says she'll marry me if we pull it off! From then on, I drive living passengers by day and ferry wronged souls, the King of Hell, and ghost officials by night, starting a hilarious life together with my fiercely protective, adorably ferocious ghost bride. Anyone who dares mess with me gets their underworld hideout turned upside down by my wife! I become a legendary underworld driver and get a red-clad ghost bride for free. What a steal!
