When Miki and Meiko are out shopping, Meiko has the idea that they should go to Yuu's store and she should buy that dress that she's been needing. The trip also has the ulterior motive to find out the real relationship between Yuu and Satoshi, who just happens to be at the store. Will Miki Get to the bottom of this rumor that is going around school?
