In this chapter, we learn that Shurishi and Sanmiyamura are rivals for the student council presidency, and that they're trying to get into each other's good graces so that they can beat each other in the upcoming election. This is the perfect time for them to be in a fight, because miyamura has a notebook full of notes that she'd like to keep secret, and it's hard to keep her under control. So, they've got to figure out a way to get rid of her, pronto. They're going to have to find a way, pronto, to get her out of her hiding place, because she's digging up potatoes in the schoolyard. Shugarashi doesn't want to see her, so he's going to go to the back gate of the school to find her. He's not going to let her out, he says, because he wants her to be part of his circle, and he wants to seal the deal by kissing her.
