La nobleza de las flores, 9

Kaoruko Waguri, from the prestigious Kikyô Girls' Academy, meets Rintarô Tsumugi, a student at the infamous Chidori Boys' Academy. The summer they begin dating gives way to a new school term, and Rintarô and Kaoruko arrange to meet one weekend in early autumn to enjoy some time together after a long break. However, four classmates from Kikyô surprise them in the middle of their date. Their prejudices against the boys from Chidori, coupled with their concern for Kaoruko, lead them to oppose their relationship. However, Madoka Yuzuhara's reaction convinces them to get to know Rintarô.
