It's the winter of Aoi's second year in university, and she's been tasked with planning an exhibition of Ensho's paintings at the Yagashira residence. As she's struggling to come up with ideas, she joins a student group aimed at bettering the city of Kyoto, and the Kita-ku ward office asks for their help in revitalizing the Mount Funaoka area. Meanwhile, Kiyotaka receives an unusual request from Atsuko, who runs a flower arranging school and an underground club in Gion, and wants him to investigate her student's fiancé on suspicion of cheating.
