I was secretly in love with Momose-san, a cute junior colleague with glasses. Tonight, due to a staff shortage, Momose-san has suddenly been assigned to work the night shift. I volunteered to take her place because it's dangerous to work late at night, but my offer was rejected because she also had the morning shift. Momose-san will now spend the night alone with a flashy guy at a late-night convenience store where there are hardly any customers. I have a strange feeling of foreboding, but there's nothing I can do about it, so I leave Momose-san looking at me with an anxious look on her face and leave my part-time job.
