During the hours when there were no customers, chatting in the back room with the cute younger colleague Uesaka-san was truly blissful. Tonight, due to a manpower shortage, Uesaka-san was suddenly asked to work the night shift. "It's dangerous to work late at night, so I'll take her place," I offered, but was turned down because she was also on the morning shift. Uesaka-san will now be alone with the playboy for the night. I hope nothing happens... Leaving Uesaka-san looking at me with a worried look on her face, I left my part-time job.
