The owner of a quiet stationery shop tucked away on the edge of town is a middle-aged man. His only pleasure in life is watching the occasional young female customer who stops by. One day, a stylish J-line girl with an air of confidence walks into the store. The moment he sees her, his heart skips a beat—but he immediately suspects she's here to shoplift, just like the others. Sure enough, she quietly slips a pen into her bag. When he confronts her, she surprisingly complies. Up close, her figure is stunning, and her mature expression leaves him flustered. As he demands, "Hand over what you stole," she pulls out the pen—and an unexpected stash of adult toys. "T-This isn't what you think!" he stammers in shock. Calmly, the J-line girl says, "If I get caught shoplifting, I get treated like a naughty girl, right?" "And if I want forgiveness, I have to do all sorts of dirty things, right?"—her words straight out of a porn comic. Suddenly switching into aggressive seductress mode, she overwhelms the owner completely. The shop's mundane routine collapses into chaos in an instant.
