After the entrance ceremony, she enters a greenhouse where she finds a gorgeous sleeping girl, Nobara Himezaki, who belongs to the Botan 'rich' girls school division. After Nobara bravely fends off a pervert intruder, Yukino doesn't meet Nobara again until the dorm room partners are shuffled, and she ends up being the only Shakuyaku girl in a Botan floor, with a Botan roomie... Nobara herself.Though starkly different, as Yukino is very dutiful and friendly, while Nobara is eccentric and quiet, the two girls find themselves becoming increasingly close to one another.
