Yuna and Samejima, who work in the same workplace, have an affair with each other, stealing their eyes and secretly seeking their bodies. They had the same dream because they had a family and couldn't meet each other freely. "I only need to do it once, so I want to have sex from morning till night without being disturbed by anyone." In order to fulfill such a desire, an affair trip called a business trip planned from several months ago. Then, on the day of the meeting, the two met at the station, changed from suits to plain clothes, triumphantly boarded the Shinkansen, arrived at the inn, and fought violently for their lips.
