Super no Ura de Yani Suu Futari

Sasaki, an exhausted salaryman, drags himself through another draining day at work. The only thing keeping him going is the thought of seeing Yamada, the bright and friendly clerk at his usual convenience store. But one evening, after being stuck in a never-ending meeting, he arrives too late—Yamada has already left for the day. Disappointed, Sasaki heads out, only to spot a mysterious young woman with piercings smoking behind the store.
