Ohayo Supermarket is a popular local hub known as the town's kitchen. There, part-time middle-aged women work the registers, their scanners beeping all day long. Among them, Keiko Yamamoto stands out as the most popular. The line at Keiko's register never ends. The reason? Her scanning speed is lightning-fast yet incredibly accurate. Her customer service is kind, polite, and always accompanied by a smile. But the biggest reason for her popularity is her stunning beauty and figure at age 45. Men approach her every day, and she often faces unwanted advances and sexual harassment. Despite being a part-timer, Keiko takes great pride and fulfillment in her work as a cashier. She is deeply trusted by the store manager, full-time staff, and her colleagues—and sometimes, that trust evolves into something more... Ohayo Supermarket is open for business and full of energy again today!
