Will Kaguya and Miyuki find a way to see each other sooner rather than later over summer vacation? And is tweeting really an effective way to communicate with your crush? Then, Kaguya's overprotective staff try to prevent her from going to the fireworks festival with the rest of the student council. Miyuki and Kaguya both try to find a way to enroll in the same elective class. And someone tries to celebrate someone else's birthday with style!?
