The Abandoned Prince's Ghost Bride

I was just living quietly alone for 300 years, and suddenly humans barged in and held a soul marriage ceremony without my consent. And of all things, with an 8-year-old brat. But this kid—can't do a single thing properly, is a total troublemaker, and just roasts potatoes to eat every single day…? Fine. Since I feel sorry for them, I'll cook them a little food. Help out a little with the laundry too—and kick them out as soon as they're all grown up. Because I have absolutely zero intention of getting involved with humans! A bizarre married life (?) story of a ghost bride, Ria, and her little groom, Lucian.
