Ran is extremely beautiful, cute, serious, a flower that many college boys dream of having. Instead of using her beauty, she starts working part-time at a convenience store to support herself. The store manager is a pervert, holding contemptuous thoughts towards conservative women. One day, not finding her bra in the wardrobe, Ran's nipples are extremely sensitive so wearing a bra makes her very uncomfortable. She decides to go braless for a day. Because her nipples are so sensitive, they easily harden, which the manager notices. A colleague accidentally bumps into Ran, causing her to spill water on herself. Now her breasts are completely exposed! Ran goes to the wardrobe to get medical tape to cover her nipples when the manager takes a picture. He forces her to obey or else this photo will be spread on the internet...
