Kana Nishida, my childhood friend who is like an older sister to me, is a girl with three things in common: good looks, good manners, and excellent grades. She goes to a famous girls’ school around here. Kana, who seems to have no connection with me, suddenly approached me one day. My name is Kaede Suo. I’m an ordinary boy who goes to a boys’ school on the opposite side of the city from the girls’ school.
