Her mother, Miki, welcomes her with a smile, but on that day, her bra that was supposed to be hanging out disappears, and her friend Satoru is suspected. Class leader Manabu learns that Satoru is under suspicion and plots revenge against the Matsuzaka family. When Manabu went to stay at Kenji's house, he attacked Miki in the middle of the night and photographed her exposed breasts.
