Ran is extremely beautiful, cute, serious, a flower that many college boys dream of. Instead of using her beauty, she starts working part-time at a convenience store to support her life. The store manager is a pervert, holding contemptuous thoughts towards conservative women. One day, not finding her bra in the closet, Ran's nipples are very sensitive so wearing a bra makes her uncomfortable. She decides to go braless for a day. Because her nipples are very sensitive, they easily harden, and 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 closet to get medical tape to cover her nipples, then the manager takes a picture. He forces her to obey or else this photo will be spread online...
