Lady Tina, this treatment is common for all of you.Lady Tina is a young and incredibly rude and spoiled rich girl, who lives by herself in a large mansion. You are one of the countless servants who tend to the lady's every need, despite her terrible treatment of all of you. But things get worse when everyone else in the house randomly shrinks, and the spoiled rich girl becomes a true goddess!
(Open to servants, maids, visitors, etc, I'll be our spoiled mistress.)
Edit: For anyone who's wondering about the first part. By lives alone I mean relatives and friends. Your all too far below her notice to count for Tina.
