A series of one-shots about four sisters, each focusing on a different sister. The first is about a good girl who is tempted to break the rules. In the second, two girls begin a pretend relationship with each other. But when one of them actually falls in love, will her heart be broken? The third story is about a student council president who's always late for meetings. In the extra chapter, Midori (from chapter 2) worries that her girlfriend has fallen out of love with her.
