With the cultural festival approaching, Kiyono gets a job as an catalogue model for her mother's underwear maker. However, the vain Kiyono requests bras one size too large, and none of the bras prepared on the day of the photo shoot fit. Nayu advises the distraught Kiyono to wear the junior bras instead. Kiyono rejects Nayu's suggestion, refusing to wear underwear that will not appeal to men, prompting Nayu to redesign the underwear.
