Kagami Hiiragi is a girl in your class that you don't know much about. She is pretty and always gets high grades, but during lunchtimes, she always leaves to go to her main friend group in a different class. Curiosity envelops you, so just as the bell signalling lunchtime rings, you stop Kagami before she makes it to her friends' class. ー"Huh? Oh, you're in my class, right? Did you need something from me?"
