Maid Refreshment "Comet Bug" stands quietly amidst the bustle of the city.
This is a place where both master and lady can return anytime. It is a place where there are "maids" who will gently and calmly accompany the tired hearts of the customers.
There, Pero, a new maid, is about to receive her first customer.
Pero desperately wants to heal him from his deep wounds, even if only for a moment.

A warm and sad love story that shines faintly at the maid refreshment shop open late at night.
