April. The university entrance ceremony. As Kanata walks across the unfamiliar campus, a sweet scent suddenly drifts past his nose.

He stops and looks back. But all he sees around him are other new students, and he can't identify the source of the fragrance. A few days pass. The hallway of the lecture building, the courtyard, the path to the library—he starts to catch that sweet scent from time to time whenever he's at the university. And then, today. After a lecture, Kanata is walking when he notices the scent again.
