Mayuko steps into a curious new world: the lingerie industry. On her first day of work the office is busy with an upcoming floor show.

The atelier's owner, Nanjo, teaches Mayuko about brand strategy. Mayuko helps her first customer and finds she has much more to learn about lingerie.

Nanjo pushes Mayuko to decide whether she wants in or out of the lingerie industry. A life-changing experience helps Mayuka grapple with the decision.
