Summer vacation is here! This is the perfect chance to get closer to Shimamura, but with no school, Adachi won't get to see her every day...So what's the plan? Text Shimamura every day? Invite her out somewhere? The summer festival would have been ideal, but Adachi's going there for work, not to hang out. Yet when she arrives, she can hardly believe her eyes as she sees Shimamura happily strolling around with an unfamiliar girl! Has a new rival appeared?!
