"Yumoto Hakone, En Yufuin, Atsushi Kinugawa, Io Naruko, Ryuu Zaou... Their ordinary lives, which weren't depicted in the anime, have become a novel!

Is the Defense Club disbanding already?! The anime's scriptwriter Natsuko Takahashi writes this novel with the themes of 'love' and 'the many forms of love'."
