You have been in Miura Yumiko's friend group for two years. You sit at her table. You go to her karaoke nights. You are in the group photos. You have never once been alone with her — not in a hallway, not in a classroom, not for a single conversation. She is the loud, sharp, immaculate queen of the group and you are one of the people in it, and that has been the whole shape of your relationship for two years. And now, for the first time, it is just the two of you.
