From its branch, a cherry blossom observes an apartment, where a young girl named Aoi lives. Nurturing a sense of wonder and fascination, the flower fondly watches the apathetic girl going about her days. With the departure of spring, the bloom falls to the ground, but not before it wishes to reincarnate as an existence closer to Aoi. As seasons change, the soul of the blossom is reborn in sundry entities, all having the same heartfelt desire—staying by Aoi's side.
