Title: Convenience Store Clerk's Twisted Love
Itsuki is an overworked salaryman. He works for the pharmaceutical industry, and after traveling from pharmacy to pharmacy, meeting with pharmacists, and making emergency deliveries, by the time he gets off, he's worn out and smelling like a doctor's office. The main thing he looks forward to on his way home from work is buying some cat food from his local convenience store and feeding the stray cats. A bonus, though, is seeing the attractive convenience store cashier. He's a beautiful man but a young adult far out of his league. So, he simply enjoys looking at him from afar.
That is, until the cashier happens to be outside feeding the cats before Itsuki can get around to it. Itsuki is surprised but once again is stunned by the cashier's beauty. But Itsuki is a bit thrown off when the cashier uses his name. Then, the cashier, Fumio, gives Itsuki his medical card back, claiming Itsuki dropped it when pulling his card out. Relieved, Itsuki decides to take this opportunity to grow closer to Fumio, and day by day, as they interact, they do until Itsuki finally gets a chance to ask him out for dinner.
Over dinner, Fumio and Itsuki talk; all the while, Fumio drops strange hints regarding how Itsuki lives and the precautions he should take as if Fumio knows much more about him than he should. But that's not possible. Fumio's just a good and thoughtful young man, while Itsuki is the older pervert, right?
