Volume 1 (Spring): Kashiwagi Yukiya lives with his son Yuuto in the home he inherited from his grandparents, a mansion surrounded by flowering trees. Takanashi lives there too, a holdover from the mansion's days as a rooming house for students. Long since graduated, he stays on because it's convenient to where he works. And because he's in love with Yukiya-san, whose secrets he's determined to get to the bottom of.

Volume 2 (Autumn): Their three lives still intricately intertwined, Takanashi is stunned by a revelation from Yuuto, and gains a clearer understanding of Yukiya-san's past. But as Yukiya-san grows more distant, nothing is clear about the future.
