JUL-674 AM 02:00 Midnight convenience store. At the parking lot, I, a night-shift worker, had my lips stolen by a tipsy married woman──. Maihara Sei

Atsushi is a young man who works at a local convenience store. After graduating from university, he continued his night shift part-time life, spending empty nights. However, something strange happens when he meets Hijiri, a woman who always buys canned chu-hi and stands in front of the store. She also couldn't stand her lonely home without her master, and spent her nights aimlessly at the convenience store. In this place that accepts anyone who comes 24 hours a day, day and night, the two end up having a relationship.
