The stage of this lesson is the sea! Fresie and his friends work hard at the seaside house to become a maid for one person.
She begs Akihito to teach her night service with Shirahane’s wisdom, but she is refused because she is still early.
However, on the way back from shopping for the ingredients of the seaside house, Filine first tells us about the service at night.
Shuri who still eats up is finally taught the service of the night, but Shirahane intrudes during her service! Filine and Laila also intrude and a service battle breaks out !?
