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!
