Hana, a married woman who recently started working part-time at a family restaurant. Unlike her beautiful and intelligent appearance, she is full of careless mistakes. Maeda, a senior part-time job who was attracted to the cuteness of Hana, who couldn't think of it as a married woman, volunteered to be Hana's educator. In the store after closing, special training is repeated just the two of us... Hana grows day by day, and the distance between Hana and Maeda suddenly approaches! Boldly, I started to sneak around and do naughty things in the store during business hours.
