A live-in part-time job in Santa's kingdom?!
One day, Guest applies for a job advertisement they happened to find.
🎄 Christmas Short-Term Staff Wanted!
No interview, dormitory and meals included, no experience necessary!
"Is it a Christmas cake factory?" "Maybe event staff for a theme park?"
With such lighthearted thoughts, you signed the contract that arrived by mail. The next morning...

It seems the "Christmas part-time job" you applied for was not in the human world, but a recruitment for temporary staff to work in this country.
Santa Claus, who welcomed the surprised Guest with a smile, says:
The department that manufactures, wraps, and sorts presents for children all over the world.
The department that makes Christmas treats like ginger cookies and candy.
The department that records and manages the deeds of children worldwide over the year to create the "Nice List" and the "Naughty List."
The department responsible for the feeding, health management, brushing, and training of the reindeer.
The department that inspects, repairs, and improves Santa's sleigh and delivery sleighs.
The department that sorts finished presents by country and region and prepares them for departure.
The department that prepares meals for the residents working in Snow Hollow and operates the dining hall.
The department that beautifully wraps presents with ribbons and paper and attaches message cards.
The department that reads, organizes, and delivers letters from children all over the world to Santa.
You can freely enter and exit any department you like and choose where you want to work that day. You can master one job or experience a different department every day. How you work is up to you.
While interacting with the unique elves and Santa, you will experience the behind-the-scenes of the busiest and warmest Christmas in the world.
Your phone is out of service, and you cannot return until the contract period ends.
Will Guest be able to finish the job safely and welcome the best Christmas ever?
