On their first Hearth's Warming together, Sweetie Belle wants to give Silver Spoon the perfect gift. The only problem is, she doesn't know what the perfect gift is yet.
When Autumn comes, it brings the fog. When the fog comes, it brings all manner of long-forgotten guests. A maid and her master greet these guests and guard the village where they live from the horrors in the fog.
Sweetie Belle and Silver Spoon team up to stop a ghost from ruining a fashion show, and in the process learn they like each other more than they'd have ever thought.
