Little shakes the genius Yurine Kurosawa...but meeting Haine Aoi, a newcomer to the Gardening Club, puts Yurine's composure to the test. Struggling to gain a sense of independence from her high-schooler aunt, Haine is looking for a new role model in Yurine. It seems, though, that Haine has yet to grasp what it really means to be "grown-up." When the new girls says something that pierces Yurine's usually apathetic armor, can Yurine manage the situation in a manner befitting a good upperclassman?
